Well ive been having various issues with a new build but while I wait to hear back from asus about some possible mobo related problems I figured Id ask a question about my cooling.
specs:
cpu: i7 2600k
mobo: asus p8z77-v pro
ram: 2x4gb G.Skill DDR3 1866
psu: thermaltake toughpower 750w (5 years old :-X from my old system)
case: antec 900 (also 5 years old from my old system)
cpu cooler: zalman 9900max-b
------
anyway, im curious as to whether my cpu heatsink is functioning properly or if I should attempt to remount it again.
and for these testing purposes Ive increased my voltage a bit just to generate extra heat for the testing. CPU clock is stock (3.8ghz turbo)
temps vary of course by a few degrees here and there during the stress testing but heres like the averages:
prime95 full load its pulling 1.344v for the cpu.
-CPU temp: 45C
-CPU Core 1-4 temps: 65-70C
idle is about 1.08-1.09v.
-CPU temp: 25-30C
-CPU Core 1-4 temps: 25-30C
1) my old cpu (an e6600) never had this much of a difference between the cpu temp reading and the core temp readings (under load).. is that normal with the new cpus? As my e6600 actually would have a higher CPU temp then the individual core temps
2) changing the cpu fan speed, from lowest setting (about 1000 rpm) to max setting (about 1750rpm) seems to have ZERO impact on temps
3) after running prime95 for over an hour, with the cpu fan on the lowest setting, the heatpipes right near the base of the cooler at the socket arent even warm. On my old system (with a zalman 9700) you could feel the warmth in the heatpipes
is this a sign that the cooler isnt making proper contact with the cpu? or is the difference between core temps and 'cpu' temp mean that the heat isnt transfering from the cores to the IHS efficiently, and if so, is that normal? or is there some sort of problem with the thermals of my chip that is making the heat not reach the heat spreader of the chip properly?
