I put CPU and GPU on the 240MM AIO but CPU temp that has lower TDP get a lot Hotter. Is this normal?

[pureexe]

My build currently running 5900x and 2080Ti. I put both under AIO (ID-Cooling Frostflow 240 and ID-Cooling Iceflow 240 VGA).

However, My CPU is hitting 80c while gaming, (85c on cinebench) and GPU is only 55c on gaming (65c on Furmark). 

This is confused me because 2080Ti has 250w TDP so, i expected that GPU will be a lot hotter compare to 5900x that has 105w TDP.

Is this normal? Or something wrong with My CPU cooling?

GPU’s run much cooler because 1) they don’t have an IHS which is an extra layer of thermal inefficiency as heat has to go from die, through TIM, through a copper IHS, through more TIM, to cold plate and 2) GPU die’s are much larger which makes thermal transfer efficiency go way up. A larger surface area to conduct heat through helps get the heat into the cold plate more efficiently.

edit:  See it now.

 

Okay so...  couple reasons:

 

1) your GPU Rad is getting cold air from the front of the case.  (Which seems to be reasonably ventilated)

 

2) your CPU Rad is then sucking in the heated air from the GPU Rad, meaning your CPU Temps will be higher.

 

Try:
1) Flipping the fans on the CPU Rad from push to pull.

 

2) Try removing the side panel behind it, and see if that helps.  (Side intakes are rarely well ventilated.)

Seem make sense to me. Does this infer that performance won't improve even i go to  bigger radiator because it a limit of IHS?

I try to flip front fan (GPU radiator fan) and it didn't have a significant improvement. CPU temp still sitting around 80-ish while gaming.

Only things to really try would be make sure the water block is mounted well, thermal paste is applied well, and not much beyond that. It’s a small case with pretty high power parts in it, it just may be a difficult thing to keep cool, and “warm” is just going to be what it’ll be.

That's not what I said, but okay.

 

Either your CPU AIO is crap, or you have a bad mount currently.

why would he want to increase cpu temps?

Push is always 1-2c better than pull

Not when Push is pushing hot air, and pull isn't.

Wait what? the same air is going tru the rad anyways?  temp of air is not changing

the front intake is the GPU Rad

yes it is.  so unless ur talking about changing gpu rad to intake too....?

the air comes in the front, and then is being pushed out the CPU Rad.

 

Why would you not want it pulling in cool outside air instead?

oh, we do want ALL rads to pull in cool air.

That is nowhere else in the thread.  Congrats, you're a dumbass.

thats what u ment ye?

It's normal, my OCed 5900X on 280mm water cooler plus D5 pump and reservoir pulls 215W and hits 85C under benchmark.

5900x get super hot super quick when using boost clocks

 

Otoh my 3080 pulling 320w rarely hit 55c with a 360mm cooler

you're being intentionally obtuse at this point.  I'm done with your idiocy.

warning ppl about bad advice = idiocy?  maybe u see it that way when ur the one doing it  dunno

This is normal. The gpu uses a much larger die which is much easier to cool.

what game was tested? whats the temps for a cpu load and gpu load?
