My 2600k temps seem a bit high

post #1 of 22
Thread Starter 
I just got my Alpenfohn K2 installed today, and it doesn't seem to be able to cool as well as I would have expected. The cooler is very close to the Noctua NH-D14 in terms of cooling performance.

I'm hovering around 90 degrees with a 1.428V Vcore in Prime95 small FFT, and around 88, sometimes hitting 90s with 1.452V Vcore in prime95 on the 8K FFT. Ambients are high 20s to low 30s. This seems higher than it should be. I'm running 3 NF-F12 fans on it (don't ask why).

One strange thing I've noticed is that the heat sink doesn't get very hot while running; it seems like the should be getting fairly warm when running; my GTX 480 heat pipes are hot enough to give first degree burns when the core is at 90 degrees, but the K2 is only a little warm to the touch when running.

One thing I suspect this might be is a lack of mounting pressure. For some reason, my Intel stock heatsink wasn't able to cool my chip very well at stock settings; it was 15 degrees above what it was on my previous motherboard, regardless of how many times I managed to mount it. Maybe the socket is recessed slightly or something. I could try putting some tape as a spacer on the mounting bar to increase the mounting pressure, but I'm not sure that's wise.

Is there anything I might be missing?

1.428V Vcore
x47 multi
99.77 bclk (my board is weird and does that)
Max LLC
1.1V Vtt
1.8V PLL

I left my case's side panel open while testing because I wanted to poke the cooler (the most scientific technique there is).

if yopur concerned about the mounting pressure you could get 4 small plastic washers to help but use them on the backplate and just done over tighten. even try a reseat maybe!?

This sounds like you have a contact problem to me, as well. For an air cooled heat sink that thing should be killing it!

Reseat temps are wayyyyy to high. What thermal paste you using?

I did 4 reseats. On the first one I realized that I has put the backplate on wrong, that dropped my temps by 5 degrees. On the next 3, my temperatures didn't really change all that much.

that washer idea won't work because of the nature of the mounting system. I think my tape idea would work, though; I just wonder whether or not that could damage something.

I'm using MX-2 by the way. Maybe I should try a different thermal compound.

ahh i see. you could try a different paste but i am not sure that will have much effect on the temps. i just cant picture your tape idea tho i expect it will work as long as there isnt too much pressure on the CPU plus tape wont short anything. maybe explain more on your tape idea and what you are concerned about.

I'm planning on putting tape on the bottom of the retention bar so that the cooler is pushed down further. The screws only go into the mounting bracket so far, so I figure this will work.

i see now, i dont expect there will be any damge caused by trying your tape method, just dont screw it down too tight is all. smile.gif

i cant say it will solve your temp issue but certianlly worth a try...
