Questions about custom cooling system.

[Kodtys]

Hi there!

Hope I come to the right place since Google didn't helped at all :( I got a question about my cooling Hydro Series™ H75 Liquid CPU Cooler - Corsair that I've been using on my GPU (NVIDIA GEFORCE GTX 1080 FOUNDERS EDITION) for about 2 years now.

Over the period of what time I should see a decrease in cooling performance? Meaning, Does 2 years suppose to effect the cooler by increasing the temperature under a full load from 55C to 70C? If not please tell me If I've been doing something wrong with the cooler itself,

please keep in mind that I'm cleaning the radiator often, Also no overclock ever been done on the card itself.

Also might be Important, to mount the cooler I've used kraken g12 mounting kit, 

I have not made ANY changes to the case itself. 

I've been able to keep 55C for over a year, then slowly it began to rise.

 

Thank you so much!

kostya.

there could be some growth inside the loop

55c full load? you must be joking (unless you have a very cool room). Normally it would be 65-75c even with water cooling .

You can check the mount. Make sure it's still tight. Remove it and change the thermal paste. If you get the same results it could be something wrong with the cooler be it either the pump or clogging/corrosion in the loop.

First of all thank you for the tips, 

You think that 2 years of cooling can somehow damage the thermal paste? meaning usually it wont change the temps for about 3~5 years or so but ill most definitely try it anyways. Cant see any reason why not.. also the fan on the mount kit itself was not cleaned properly due issues of space.

I'll unscrew the cooler and try to clean it.

Also no one really answered about me asking how long should a cooler start being ineffective (decrease in performance)

Not usually. 55C is actually the upper limit of an average estimate. Source: My loop has my GPU at 50C under load

 

Anyways @Kodtys , cooler degradation can happen after variable periods of time, and is influenced by the cycling of temperatures etc.  Might be just time to get a new one. As it is an issue that has procedurally been augmented, it safe to say it's not an issue with contact but degradation.

I assume you're referring to just liquid coolers. It really can't be said. There's no set "standard" of when they stop performing as good as day 1 it's going to vary cooler to cooler, manufacturer to manufacturer.

 

It can't be said for sure the cooler itself is going bad but there's only so many variables here and the cooler itself would be suspect number one.

Really? My RVII (GPU, not hotspot, that hits the 90s at max voltage) sits at around 60-65C under full load and I don't have a massively overkill loop. From what I've seen of 1080s, they usually sit in the 50s on a custom loop. 

[Kodtys]

Is it possible that if Im running a stress test (MSI Kombuster and FurMark) both of them at 97~99%, the max temps are 61~63 

but if I'm running metro exodus I'm in the area of 70 give or take

[Kodtys]

Ok so finally I figured out how come my temps jumped so high.

About a year ago I bought new cpu and rearranged the cables, after i turned the system my gpu cooler fans worked at 100% because they were connected tp the PSU (2fans). Since it was noisey IVe decided to connect both fans with a switch to the motherboard and it did helped.

Thing is I realized that the fans working at 20% tops no matter the temps. No matter what software I tried to control it. It seems to not care and keep spinning passivey regarding the temps.

For now Ive connected the fans back to the PSU and its 55~57 again.

But they work at full speed and pretty noisy. Any suggestions?

Out of my 5 1080’s 50c would be worse case. 

 

With 3 on a loop mining, I’d keep the fluid at 45c max. Going over 50c on the cards but barely. Depends on the version and bios. 

 

A lot more variables in an aio though.
