i7 4770K running hot?

[dougolada]

I have recently built a custom watercooled loop to try and reduce temps, mainly CPU, but I'm not happy with my results and would appreciate some advice.

When running the OCCT stability test with all BIOS settings set to default values, the CPU temp goes to over 80°C within a few minutes and if left to run, the system BSODs.

I know this isn't right but am not sure where to start with finding the cause of the problem.

My system can be seen here if that helps...

Yea I can feel the pump running. I've got no idea if the water is flowing though as it looks completely still but I'm assuming that's just because there's no air in the loop...
Not sure how hot it goes on gaming, will try and let you know.
I am wanting to overclock the system hence using the stress test so should I just use a game as a stress test instead?

will re-seat the CPU cooler and clean and re-apply the TIM, lets see what happens...

I'm an idiot! I haven't removed a plastic film from the CPU cooler. I didn't notice it on installation but when I removed it I thought the spread of TIM looked odd so upon closer inspection found there was a layer of film... Whoops!

Yea, slightly embarrassed but very relieved

Tbh, ive done this myself a few times. How are temps now? Btw, just had a read through your build log. Very nice setup.

Temps are much better, roughly 25°C cooler!

Thanks for the feedback

They probably use plastic that doesn't melt easily for this very reason.

It would certainly appear so as the plastic looked as good as new, apart from the TIM on it...

It varies according to manufacturer. Ive had some heatsinks that have had a stiff plastic cover, others just used a thin film of plastic. Thermalright ones came with a warning to remove it before istallation printed on it.

The XSPC Raystorm seems to have both which is why I missed the thin film...
