im buying a e6850 cpu will my akasa evo 120 cool it well (i will NOT be overclocking)

any one ? i dnt want to fry a new cpu :mad:

If your not overclocking then stock cooler is just fine

i just want a quiet computor and i already have the akasa evo spare

The Evo 120 will do fine at stock speeds. Have owned one before, it's quiet but awful if you plan on doing much overclocking.

Is it a rev 1 or rev 2 Evo 120?

The rev 1 hits its limit much earlier and I wouldn't care to use it on a 6850. It would probably be just about OK at stock, but watch your temps under load. It's a very good cooler up to its limit, but performance plummets afterwards. I had one for my A64 3000 with a 25% o/c to 2.25GHz and on minimum fan speed the Evo kept temps to ~45C full load. I then put it on an A64 X2 3800 at stock (2GHz) and temps reached 57C/63C. Changing the fan speed from min to max had no effect on one core and dropped the other by only 2-3C, so it looks like the issue is the amount of heat that the heatpipes can carry from the heatsink to the cooling fins (rather than the amount of heat that can be carried away from the cooling fins).

The rev 2, I'm told, has much wider heatpipes.

its the rev 1 i was using it on my 4800 x2 and kept temps @ max 45 full load and around 32 idle what are the recomended temps on these 6850 chips ?

how loud are the stock coolers on the e6850?

krisbutler · 24 Jul 2007 at 18:07

basicly would this be safe to use at stock or would the stock heatsink fan cool it beter?

That's odd, as I have a rev 1 on my X2 3800 and it hits 57/63 on full load.

And your room and case temps are?

I don't have a thermometer in my room, but I'd guess at low-mid 20s at the moment.

Speedfan registers two temperatures (in addition to the cores and the HDD). They're at 37 and 43 after a while running Othos small FFTs. At idle, they are 37 and 34. I suspect that the latter is the reading from the sensor among the power regulation components.

The cores are 40/42 at idle (well, with a couple of browsers running).

I'm using MX-1 paste. I tried the rather large amount specified in the instructions and a much smaller amount, the amount of thermal paste I'd usually use (cleaning the heatsink and CPU in between, of course). The instructions seem to be right - temps were ~2C lower with the large amount of paste.
