Getting rid of heat

stuie · 2 Jul 2013 at 11:37

Ok so my 3770k is still running hot, Ive reseated the block 3 times with fresh new as5 Ive got plenty of rad space but im just not able to get the heat off the cpu. While in ibt my cpu hits up to 80c even on custom water with plenty of raddage however the rad temps are only hitting around 35ish so I know its an issue getting the heat away from the die.

Would changing from as5 to CLU help much or is delidding the only way to really get the temps down? My only real issue is for folding, when leaving it on over night with both cards and the cpu loaded it hits about 83c and crashes the cpu folding core everything else is fine so ideally id be happy just dropping around 5c off to get it fully folding stable

Should have added this is running 4.5ghz at 1.32v but 1.208 loaded with prime after droop and that this has only been an issue in the last couple weeks since the wamer weather

Hi, how's the air flow in your case and have you checked for any trapped air in your loop as this will effect your temp's?

Seems like air could be the culprit if you have decent rads and CPU block is seated correctly.

How long did you bleed the system for?

Delidding is your only real option I suspect.

Systems been running for about 3 months and ive unscrewed both the rad tops which started seeping straight away rather than letting any air out i am loosing a touch of water still out the xspc res (approx 2mm a month) but Ive read that can be described as normal for most systems.

If your power can handle it and the rads also, a peltier may be an expensive solution.

Delidding would be my choice and running it naked

you might lose a further 3-4c if you used liquid pro where you'd normally apply thermal paste

if you managed a successful delid however and used the liquid pro under the internal heatsink/ontop of the die you see anything from 15-20c drop

using an offset voltage rather than a fixed cpu voltage will help aswell as the cpu isn't running full voltage/heat all the time

Due to the crappy paste used in Ivy/Haswell, there is no real difference between a mid-range air cooler and high-end watercooling. The heat simply can't be transferred from chip to block fast enough. De-lidding is the only solution but do so at your own risk.

I found an old blister pack I can cut up would that work to cut through the silicone but not damage the pcb?
