Why are my temperatures so high?

[SonLux]

Is there any outstanding reason that my GPU is running 50 degrees at idle and all the way up to 90+ under load? It is an MSI 980ti that is not overclocked. My i5 6600k overclocked to 4.5ghz maxes out at 60 degrees in the same cooling loop. There is one 360 rad at the top of the case and a 240 rad mounted to the front.

Do you have a pump working?

Is your pump functional?

D5 pump working fine it seems, changed from a DDC for a sake of a quieter pump although its running at 100% to maintain that 50 degree idle temp.

it's probably a bad mount. you'll have to take the block off and put it back on. also double check thermal past aplication

I've also considered re-routing the loop to have a rad before the GPU, would this make much difference or does the order not matter too much? I'll re-affix the block and see how it changes.

I agree with Squinty it sounds like an issue with the block not being able to pull heat off your components, if it was a pump issue your cpu would be on fire too.  You can probably get away with dropping your pump speed to around 2.5-3 as well, depending on where it resonates with your case to increase its longevity.

Dropped the pump down to 50% for about 15 minutes now and the GPU temp has gone up to 65 at idle while the CPU is still around 30 so that certainly lends credence to the idea that it's the block at fault.

[MSN04Sazabi]

Pump speed really only makes a big difference when you have a lot of blocks to cool and require the extra head pressure. The faster the water goes across the block the faster it goes through the rad too.

that won't change anything that's a common misconception of how watercooling loops work. it might drop a degree or two but it's not what you're looking for

That saves me a lot of work then, easy enough to re-fit the waterblock, I'll probably change out the tubing from GPU to rad as that has warped from the heat and weight (detailed in another post)

[MSN04Sazabi]

What version 980Ti and Waterblock do you have, because it doesn't look like the reference design with that 8x8 pin power.

[MSN04Sazabi]

Its a MSI AIB but it should be almost mirror to the reference with the titan block on it, doing low 60s under load.

MSI GTX 980 Ti Gaming 6G card and EK-FC980 GTX Ti TF5 block

Is the semi prolonged use at 90 degrees enough to cause this warping to the tubing? Or is there another factor I'm not considering, it is only happening at this fitting from the GPU to rad. 

 

[THFourteen]

That seems very high for that GPU. Mine (Palit 980Ti) idles around 30 and only goes up to 55 in Unigine benchmarking and that’s with some reasonable overclocks. 

 

Something is wrong I can tell you that much altho you already knew that :-)

[airdeano]

prolly the GPU processor isn't pasted well enough or you have one large air bubble trapped in the GPU block.

[dual290x]

Sound as if you have an air bubble, not enough paste, or the block is getting clogged up.
