Cosmos Vii Cooling?

[uzzi38]

Hi,

I just recently got the Cosmos Vii with a GTX 1050ti and i5 8300h, and also with the Cooler Master thermal paste as well.

Issue is, with the charger plugged in, I've been noticing CPU temps of about 60 degrees Celsius whilst idle. On battery power its fine, the CPU undervolts itself to a 1.3GHz clock which is great, because it helps preserve battery, but the core clock when plugged in is higher than normal afaik.

Furthermore, whilst gaming (specifically playing a game called Planetside, which is notorius for being incredibly taxing on CPUs whilst leaving GPU workloads relatively lightweight, my CPU has been turbo-ing up to 3.9GHz, which is great, if it weren't for the CPU going up to 95 degrees. Safe to say, I ThrottleStopped the hell out of it, and dropped the turbo down to 3.2GHz, cooling the laptop by about 20 degrees and also making me lose out on about 20fps in the process too. Sad times.

Which leads me onto my questions - is this normal for the Cosmos lineup?

Also, is it possible to use liquid metal to cool the laptop further, and what kind of temp improvements should I expect? Because another thing I noticed is that increasing the fan speed didn't lower the temperatures - it feels like the thermal paste isn't effective enough to transfer all of the heat off of the CPU.

Thanks in advance

I doubt it, the Cosmos only comes with a GTX 1050 non-ti? The laptop 1050s sometimes have 4gb VRAM I think if that's where the 1050 ti comes from?

Anyway...

Have you tried using throttlestop to undervolt the laptop rather than capping the frequency? You may be able to maintain the same boost frequencies but with a lower voltage, reducing temps, power consumption, etc

95 degrees, while within spec for the CPU, is not what I personally would describe as a healthy temperature - especially under gaming load which I assume still isn't actually 100% load.

I can't say if it's normal for the chassis, as there have been relatively few comments on the Cosmos on these forums (generally it's not been best value either) but given you're the first person I can recall who has posted about 95 degrees C temps under gaming load for that chassis I'd say it's probably not usual.

Yeah, the GTX 1050ti was a type. Meant 1050.

Onto the issue itself. I wanted to point out the game I was testing this with is intensive of the CPU moreso than the GPU. A GTX 1060 can max out the game on Ultra settings. I'm playing on all-low. So the load is, in-fact, at near 100%. At the least, it is on one core, with the others about 50%

Without ThrottleStop, my temps sit about 95-ish in game and 65 degrees when idle
With Throttlestop active it drops to 70 at 3.2GHz, and idle to 45 degrees. My issue is, I also lose out on a signjficant amount of FPS at the same time.

Also, I was fine with the Cosmos being a low-end device for regular gaming. Never had an issue with it because nothing I play requires a better GPU. To prove the point, this GPU sits around 60-ish degrees in game, and regardless of settings, stays there.

My issue is, increasing the fan speed hasn't helped drop temperatures. I wanted to see if others have had similar issues and whether or not liquid metal application is possible for this laptop.

I would personally say those temps are too high. Again whilst in spec for the CPU, it shouldn't be that high on idle or maxxed out, I would say more like early 40's tops on idle and high 80's to early 90's on full load.

It's possible the thermal paste has a bubble or just hasn't been applied optimally, before thinking of liquid metal (which I doubt would be supported on that alluminium heatsink), I would try a repaste.

I haven't taken apart the laptop in the fear I might make an incorrect judgement as to what the heatsink is made of. An aluminium heatsink means I can't liquid metal it then - any contact between the die and the heatsink would eat away at the hs :/

Gonna have to buy me some thermal paste then. Bit of a shame, considering I got the laptop just a few days ago. That being said, my overall experience has still been pretty good. And I'd argue its well worth it price wise. Dual channel ram, an SSD and a HDD and I get it all for under £800? I'll take it thanks. Especially when I needed a better CPU over a better GPU in my laptop.

This does sometimes happen unfortunately, the paste just isn't applied correctly, or forms a bubble which is just unlucky and can't really be avoided.

If you're looking for a good paste, I've been using Thermal Grizzly Kryonaut for a couple of years now, used to use Arctic Silver but I do find a noticeable improvement with the Thermal Grizzly.

 

[uzzi38]

Thanks for the help. Thought I'd do a little report back on it.

The Thermal Grizzly Kryonaut was brilliant. My idle temps went down to about 45 degrees with it applied. I'll also provide some Cinebench benchmarks:

Before reapplying paste: 781
After applying paste and stressing the CPU a few times: 776. This score remained consistant for a while.
After leaving for a few more hours: 801.

After some more serious undervolting, this got pushed up to 840. If I use other's undervolts as a reference, there is a solid chance this can be pushed even further - mine is at -130mv currently, whereas others have safely pushed past -150mv.

Also, one more thing: the Cosmos VII comes with a copper heatsink and pipes (or at the least, mine did). So it is possible to actually use Liquid Metal. I personally won't - not certain if its worth the extra hassle and cost for an extra 5-10 degrees right now, but if anyone else is interested I thought I'd bring it up.
