Is a Corsair H80V2 AIO cooler sufficient for a 3900x? (No overclocking)

[PutridPlanet]

Hi i have a few questions about the Corsair H80V2 on the 3900x.

The Corsair H80V2 is a dual fan 120mm AIO which has a extra thicker radiator which i hear is not your ordinary 120mm AIO so
has closer performance to a 240mm AIO.
It has been extremely difficult to find information about it online and i don't know exactly what to believe but from what i know It is only slightly worse than the Corsair H100i which has the same amount of fans but a larger radiator.


1. What temps should i be getting while gaming on average? (I know case air flow matters but would like an estimate with this cooler)

2. If the TDP of the 3900x is 105, Should the Corsair H80V2 be able to dismantle that much heat?

3. Even though a 240mm AIO would have better cooling potential, Is it only needed if i plan on overclocking?

4. Will temperatures over 80c affect the lifespan of the CPU or will it only affect it once it hits the limit which is 95c?

5. Will the Ryzen 3900x overheat and will my computer shut down if my temperatures get higher or will i just run into thermal throtting instead? and will thermal throtting mean lag in games?


Note: Please may i ask for proffesional responses to this and not for anyone to reply and tell me that AIO's are garbage and leave a biased response telling me to get an air cooler. I am not concerned about the debate about AIO's and air coolers, I simply want to know if the cooler i have should be fine for stock use and for gaming purposes/music production. (I am sure that it must be better than the Wraith prism at least)
Thank you.

Hiya

We can't comment on individual components as they all inter relate.

If you can post the full specs you're considering then we can advise.

Alright that's fair enough. Thanks for letting me know. Do you work at PC specialist? Sorry i am new here, but my PC specs are

CPU : Ryzen 3900x
GPU : Nvidia Geforce 2080ti
RAM: 32GB
Motherboard: ASUS ROG STRIX 570F Gaming
Power Supply: Corsair 650 Gold rated TXM series
Cooler: Corsair H80V2 Hydro cooler
I also have a 2TB Seagate HDD and a 2TB Intel SSD as my primary drive.

The 3900X usually comes with the Wraith Prism cooler but for the 5900x more higher end coolers (240mm AIO minimum or a higher end air cooler are more suitable) from what i know.
I also would like to know if the 3900X runs cooler than the i9-9900K and if the 3900x by default is overclocked.
A few people have told me my cooler should be sufficient with decent case airflow but there is an awful lot of criticism about 120mm AIOs too online despite the fact the H80V2 has a thicker radiator and is basically just the smaller brother of the Corsair H100i which is a way more popular cooler...It's not the best cooler of course but if it will be sufficient then i don't mind despite it is rather loud when the fans ramp up. That isn't really much of an issue to me as i wear headphones.

Hi there. Yes it is, but please keep in mind this is a build i ordered about three years ago named the "Fusion Ultra" which is why i am talking about a 3900x here and I don't know if you are able to backtrack the default specification for the fusion ultra you had listed here in 2019 but I do not remember changing the cooler at all. I only remember adding more hard drives. I assume that this was the default cooler for the fusion ultra now since it has been changed to a 5900x and 3090ti it appears to have changed and since then the Corsair H80V2 has became out of stock...basically obsolete.

Even though a Corsair H115i would be a lot better, surely nothing bad would happen right? just a bit more noisy? right?

No need to keep opening new threads, just comment on the existing and bump it if necessary.

You can see for yourself what temps it's running at.

But with that cooler, you will 100% not be reaching the speed possible, it will be throttling back pretty early I would guess, so you'll be missing out on a fair bit of performance.

It's not a good idea to use a CPU under throttling long term as it can damage the CPU and or motherboard. Also, the cooler is likely to fail early as it will be operating under a far higher load than it's designed for.

Are you sure about this? This cooler does have the same amount of fans as a H100i or H115i but just a smaller radiator, I was under the impression it would just be a bit louder because of this. Thermal throtting on the 3900X is supposed to happen at 95c. I don't know how it would ever reach beyond 90c apart from in stress tests. The H100i is about 5 to 10 degrees cooler on average. Others have told me it will be sufficient with good airflow in the case. If it is really bad performance or fails i'll get a H115i put in instead of course but there are youtube videos i have seen with the wraith prism being used on a 5900x where gaming loads was reaching not beyond 75c. PC Specialist basically listed this cooler with my build when i got it, it was the default specification.

 

[PutridPlanet]

I asked five questions but nobody here answered them. I mean anyone can assume anything of course. I can assume that you need a Corsair H150i for a Dual core intel proccessor, but i'm looking for proof of all of this. PC specialist basically have a different opinion and think it is sufficient. Of course a bigger cooler would perform better but if AMD believe even the Wraith Prism can handle it then i believe this is a overreaction.

 

[PutridPlanet]

Of course this is not reccomended at all. If i was choosing a 3900x myself i'd get the H115i and for the 5900x i'd get a H150i but PC specialist put the H80V2 on their default specification so i assumed it should be adequate. I was going to change my power supply to 750w but they said 650w was also fine. In this video the guy is playing shadow of the tomb raider with the Wraith Prism on a 5900x and is getting around 75c. With everyone claiming different opinions I'm not quite sure who i can believe so i basically just want Proof.

I guess there's not anything else we can say as it's all been said. It's up to you how you want to proceed.

Fans are of no relevance, it's the radiator size and pump effectiveness.

I am not denying that the H115i is a better cooler at all and i am not implying that using a smaller cooler would be not be more noisy and that you would get less performance but i doubt it would be that much of a drastic performance loss and i am assuming you are just guessing here of what you think will happen but have not tested this before. PC specialist basically listed that cooler with the 3900x....so you are moderating a forum owned by a company who has a different opinion on this. I will get a H115i with future builds or if there is any issues with the cooler i have but you seem misinformed as thermal throtting does not damage a CPU. I am no PC expert but even i know this.

 

[PutridPlanet]

I asked five questions in my original post, I wanted to get opinions from various tech experts here but it doesn't really look like i am in the right place right now so i'll leave it at that.

 

[TonyCarter]

I'm not a moderator, nor an expert, just a customer of PCSpecialist (my build is in my signature) who spent months watching Youtube videos, reading PC building forums and listening to conflicting advice from almost everywhere.

What these youtube reviews don't do, is run that same cooler for 12 hours a day, 7 days a week, over the course of a year to see if the components hold up. They do a couple of runs over the course of a day/week and say 'no problem'.

If you want something to last longer than that test period, then you over-spec a little to ensure you've got the headroom.

The PCS configurator will list all the parts 'compatible' with each other...but does not say which will work best together...that's where YOUR research/choices come into play...as only YOU know your usage.

For example, PCS will let you put 2400MHz RAM in when everyone knows you need 3200MHz+ for gaming...but if it's for an office PC, then 2400MHz may be fine. Same goes for coolers...if the CPU is going to be used for office work/light gaming then the standard air cooler may be fine, but for video rendering overnight a cooler with much more cooling capacity would be better.

However, as random people on the internet, we can only advise what we think is the better/best solution from our own experiences, and it's up to you to decide whether you believe us or not.

I'l try to answer with my non-expert views:

1. What temps should i be getting while gaming on average? (I know case air flow matters but would like an estimate with this cooler)
You already have the cooler & CPU combo you are asking about (your system must be a few years old by now), surely you're in the best position to TELL US what temps you're seeing on average in your specific workflow/gameplay and whether you're seeing any throttling yet?

2. If the TDP of the 3900x is 105, Should the Corsair H80V2 be able to dismantle that much heat?
I can't find the spec for the H80v2, but if the H80v2 can dissipate 105w at peak then you'd want something with a higher capacity so that it's not working at full speed all the time (which wears everything out faster). Also, it's not just SIZE that matters, it's also the quality/performance of the pump/fans - in this case the H80i has the older SP fans & pump and is designed for SFF build, the H100i has the newer/better ML fans & pump.

3. Even though a 240mm AIO would have better cooling potential, Is it only needed if i plan on overclocking?
Cooling helps in all scenarios, not just overclocking

4. Will temperatures over 80c affect the lifespan of the CPU or will it only affect it once it hits the limit which is 95c?
Until someone tests the lifespan of the CPU/AIO at constant 50º vs 60º vs 70º vs 80º vs 90º vs 100º in a closed case (not an open bench rig or AMD lab), then we can only assume that cooler is better in the long term. But I'd say if you're keeping it below 90ºc then it won't affect the CPU...HOWEVER the AIO will be running at max and you'll kill the pump/fans sooner.

5. Will the Ryzen 3900x overheat and will my computer shut down if my temperatures get higher or will i just run into thermal throtting instead? and will thermal throtting mean lag in games?
It will thermal throttle before it does any long-term damage, however if it is constantly throttling it means there's not enough cooling/airflow (or bad paste if it's not been repasted for a few years - or if the system hasn't been dusted out regularly)

To answer these as best as I can

1. No idea, depends entirely on settings, resolution, the rest of the components in the build, where the computer is stored, etc, etc, etc

2. TDP isn't accurate and never has been

3. 240mm Radiators are generally where you want to be, bigger doesn't offer that much heat dissipation and smaller doesn't offer enough. The pump is also critical in being able to deliver the fluids around the radiator effectively

4. 80c is fine, 90c+ is where I would get concerned

5. Thermal Throttling will happen first but if the cooler dies or get's burned out it wont be able to cool at all and the computer will start to turn off. Thermal throttling will lead to reduced and inconsistent performance

Thanks for clarifying more, That's much better. I do know that the H80V2 is capable of dismantling more than 105w but can't find the exact amount online. I do assume it is at least 150w at minimum but if you are telling me that doesn't matter much i wouldn't be concerned much then. It's basically an obsolete cooler. They don't sell it anymore but PC specialist reccomended it with a 3900x build even though 240mm AIO would be more suitable so at the time, being someone that didn't know much about cooling I basically trusted the default specifiation. It is more suited for SFF, I certainly would not overclock using it though. There will be problems if my pump breaks or if it leaks to which i will then get a H115i. I agree with you that 90+ is something to be concerned of. I don't plan on using Blender 3D or anything like this. I just wondered if anyone had tested the H80V2 with a high end CPU like the 3900x on gaming loads. Corsair told me to expect 70-75 on full loads with this cooler.
The Wraith Prism would surely perform worse though, so if its not adequate i don't know why AMD was selling it with the 3900x.

 

[TonyCarter]

PC specialist reccomended it with a 3900x build

Was this a PCS salesperson on the phone, or the configurator?

If it was the configurator, then it's NOT a recommendation...it's simply a list of COMPATIBLE parts that may or may not be suitable for your use. I agree that having no way to tell whether they're good enough or not is not great, but that's where the forum can help (before you click buy, obviously).

I do know that the H80V2 is capable of dismantling more than 105w but can't find the exact amount online.

Corsair don't publish the TDP for their coolers...probably because TDP is a very dodgy way to measure heat (Intel just lie, AMD are slightly better - hence the lack of trust you'll see from some on here against Intel's claims).

The only benchmarks I can find with the H80v2 vs the wraith, show about a 5ºc drop at 65-70ºc. Not huge, but it all helps.

Here's an 'average' cooler temp chart for a 3800x (from GamersNexus)...sadly no H80 listed:

Corsair H100i Pro Review vs. H100i V2, CLC 280, & More | GamersNexus

stub Corsair’s H100i Pro is the third Corsair product to use Asetek’s 6th Generation pump solution. Asetek didn’t push performance in significant ways with 6th Gen, but instead focused on endurance improvement and reducing hotspots that encourage permeation of the tubes. This time, just to keep...

www.gamersnexus.net

From quick research/browsing, it seems the H80v2 (Gen 5 pump), H100i Platinum (Gen 6 pump). The generational changes seem to be around RGB, slimming the design, increasing endurance and reducing hot-spots on the plate.

If you're thinking about replacing the cooler, then the minimum you could probably buy that is 1) not discontinued 2) that is compatible is the H60i...but the recommendation would probably still be a 100i/115i to keep it cooler, thus quieter. Of course, if you're planning on upgrading to a 5900/5950x then a 150i may be the better route (assuming it will fit in your case/config).

 

[PutridPlanet]

Yeah i agree, I guess i could just use the H80V2 in the time being unless the temps are reaching beyond 90c with it which i suppose could happen if the pump does break as they usually do eventually i think. If anything happens i'll get a H115i to replace it now i know more about cooling solutions but for a 5900x or 5950x a H150i would be more suitable i think as i am planning on getting a new PC in the future anyway.
