Mega 2600k problem, high temps at low voltage - Page 2

post #11 of 20
I would start over, beginning with cleaning the cpu and water block with something like ArctiClean. After you know both surfaces are clean, apply fresh TIM in the middle and be sure to apply proper pressure to hold the block to the cpu. If you had great temps previously, something obviously changed and the only way to narrow it down to the cpu would be to be sure everything else is done right. I went through this process a few times and finally got it right, running a 990x at 4630 MHz on Prime95 at 58*C.

One other thing I found (at least with my setup) was when I overtightened the water block my temps actually ran a little higher.

Open a window try to get ambient down to 25C or so.
70C ambient is quite warm
you will notice a big difference in temps with a 45C drop in ambient

It can definitely be a cpu that runs hotter, just need to narrow down all the other possibilities before trying to RMA it. Unless the waterblock is older and hasn't been cleaned (used tap water and it got nasty, something like that), it shouldn't be impeding flow. How about air in the system, is it all bled out? Air trapped in the block or the rad can definitely contribute to higher temps.

try the stock air cooler and compare to see what's defective in your system.

ok, the block is 2months old, only ever used distilled water. So cant be that? can it be anything else? the pump is working, all fans are pulling cool air into the rad.

How is a chip running hotter than another cause for an RMA? It's not like they are guaranteed overclockers. Some perform better than others but that doesn't mean its actually defective.

That's weird, mine runs much cooler under just air. My ambient is around the same, running 4.6Ghz @ 1.462 (max, it jumps around a bit) and I get temps of about 70C. It was previously under a Megahalems at 4.8 hitting 70C with less air through it.
