Gpu hot?

[DominicNikon]

Hello, I had a gpu water block installed from microcenter and the average temperature underload is 75C and I believe for an RTX 3080 with 2 480 radiators this is way too hot and I think it should be around 45-50c? It hit 80c once.  Does anyone have any suggestions?

Two 480mm rads? What case do you have a Corsair 1000D? 

 

It may be too hot for your liking, but the GPU probably doesn't care all that much. And was this a pre-waterblocked card I assume?

Yeet your radiators and get a water chiller, you can get subzero temps even if you have done proper insulation on the board and gpu so no condensation

 

 

Ok lets be real here, complaining about 75c is bs, dont even bother with trying to make it cooler, it already runs quite cool

It's not. Microcenter put on a ekwb vector ftw 3

Isn't that laptop hot?

Is this a brand new loop? Are there other devices in the loop?

Laptop gpus run at 95c just fine

 

75c is quite a low temp for gpus so fussing about something that the gpu doesnt care about is not worth your trouble

Just a cpu block. The loop was already in just a cpu configuration and the addition of the gpu block increased the cpus idle temp by about 10C

75c is warm considering 80c is the most used number for a gpu that's too hot

Bruh stop worrying about it, gpus will handle 95c just fine, even 105c in some instances

 

Like i said if you want a cool system then go buy a stupid water chiller and stick that in your custom loop, pref set it to 20c so no condensation

 

Again completely uneccesary unless you are an ocing nut like me and push your components to their limits

A lot of misinformation here. 75C is way too high for a watercooled gpu. With 2 480mm radiators the coolant temp is probably <10 degrees above ambient. GPU block should cool your gpu to ~15C above coolant temp. Your gpu temps at highest should be low 60's, high 40's to low 50's is what I'd expect with the raddage you have. The issue probably has to do with the gpu waterblock mount. Could've been that they didn't tighten it enough, not enough thermal paste, or forgot to remove a sticker. You could probably go to microcenter and tell them that you're hitting 80C with 2 480mm radiators and they should remount it for you. Or you could just remount it yourself.

Thanks for the information. Do you think it could have anything to do with air in the loop?

That's another possibility. Do you see any air bubbles in your waterblock? The other 2 possibilities are pump is not spinning, or fan rpm is way too low but I don't think either are the case. To get air bubbles out of your blocks set pump speed to 100% and tilt your computer in different directions.

I've been shaking the case and getting bubbles out. My cpu which is after the gpu in the loop gets up to a Max temp of 65C under cinebench r20. It's a Ryzen 9 3950x. So I was thinking if it was bubbles or pump the cpu would have been hotter? Also I was looking at my receipt and the thermal pads the guy at microcenter used were not the correct sizes in terms of thickness according to the manual, could that be an issue?

So if air bubbles are in your gpu block then that will only affect your gpu. If you have air bubbles in your cpu block it'll only affect cpu. Thermal pads are for things like the memory on the gpu. the temp reported as your 'gpu' temp will be for the actual core which should have thermal paste. The pads is concerning though. I'd download hwinfo and look at what your memory junction temps are and make sure they're not hitting 110C under load which is supposed to be the highest your memory should hit. With watercooling and decent contact it should be less than 105C at the very least

Those temperatures are not close to 105c. Should I give it time and see if air bubbles make it out of the gpu block or should I take it back tomorrow and ask for them to remount it?

If you just assembled the loop give it a day or 2 with pump running. If there are some air bubbles still they'll be gone by then.

This is the answer.  The block isn't mounted well to the GPU to have a 75C GPU temperature unless your water is getting up to 50C, which would be un-possible with a single 480mm radiator.  It could be something as basic as them installing too thick of thermal pads on the VRAM which flexes the block away from the die.
