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

[PutridPlanet]

The options in the PC building configurator listed the H80V2 with the 3900x a couple of years ago with a PC named the Fusion Ultra and since i knew nothing about cooling then i assumed it was fine without knowing this forum even existed. It has been removed now though alltogether. You have an option to choose a better cooler or a worse one but the H80V2 was listed with the 3900x back then as the default reccomendation.

Most pre-built configs are done to a budget. The headline elements (CPU/GPU) will be where the money is spent...and the other bits will be the bare minimum they think they can get away with...always with the option available for the customer to spend another £10-£1000 upgrading individual components before they click buy.

If you're thinking of more powerful CPU, and GPU, then you're then also having to put a more powerful PSU in there as a 650w one will be underpowered for a 5900/5950 level CPU and 3080/4080 level GPU combo...and when I say 'underpowered' I mean that it won't be running at it's optimum efficiency if you're using 100% of its capacity (most efficient in the 40-60%). But again, unless you're running it near its max for long periods of time, not usually that much of an issue.

But if you're thinking of going that far, then you may want to skip to the next generation and go for the Zen 4 Ryzen range (7800x for example) with an all new motherboard/power supply/GPU???

Decisions, decisions

Yes, For a 5900x or 5950x system with a 3090ti, 650w wouldn't be enough https://www.whatpsu.com/psu/cpu/AMD-Ryzen-5950X/gpu/NVIDIA-GeForce-RTX-3090 according to this website for a 3090 and 5950x you would need at least 700w, but for a 3090ti it will be more...i'd personally not want less than 800w at the minimum. PC specialist reccomends a 1000w power supply for that build. 650w is enough for a 2080ti and a 3900x but it's just like the cooler situation at the end of the day.....a H115i would be better than my cooler just like how 750w would probably be better for my current PC. If the temps on average are 65-70 or 70-75 while gaming with the H80v2 that is totally fine. If it went over 90c i'd definitely need to get a better cooler though. With the H80V2 there may be slight performance loss but i don't think it would be too noticeable. I may as well wait until it breaks to replace it with a better cooler right?

Nvidia themselves recommend a 850W PSU for the 3080 alone mate never mind the 3090. Most people are speccing that as the minimum these days they have gotten absurd in the power consumption

Extremely bad idea, if it breaks, it has the ability to take the whole system with it.

Well everything is going to break eventually, If it leaked or something then maybe. Everyone believes the cooler is sufficient though. I don't think i'd ever see temps over 90c unless the pump failed and it wasn't cooling properly. It's a bit noisy for sure but that guy said he saw it staying 65-70 on gaming loads.

I can't tell if everyone at least in this forum is saying that i must replace the cooler right now because it is a risk to the PC or something. I unfortunately do not know how to replace it myself. It's hard to me to know who to believe on this...some say it's sufficient....some say it's not...as long as it cools it and doesn't cause the PC to overheat then that's fine as far as i am concerned.

Also do you only need to apply thermal paste if you use the PC often? isn't it already pre applied on the cooler? Yet again i have no clue how to do this but i guess at some point it will need to be done.

If you really can't tell when you've had 3 people saying the same thing then I'm afraid there's nothing we can do.

Corsair coolers come pre applied, but if you move the cooler you have to re apply.

I'm going to lock this thread as it's going nowhere.
