I recently bought a core i7 930 and have tried overclocking. I have tested on prime 95 for almost 10 hours now and there have been no errors. I am unsure if the temperatures are a little bit high though. I had a zalman 9900 and was getting load temps of 80 degrees at 4.0 ghz with 1.256 core voltage. I replaced the zalman 9900 with a Prolimatech Megahalems and was able to drop my temperatures by 8 degrees celcius to 72 degrees C for the hottest temperature on my hottest core in Realtemp. The highest temps for each core are: 73/73/71/68. My core voltage is measured by CPU-z 1.53.1. My temps are measured through Realtemp 3.46. Do my temps seem too high considering the voltage and the cpu cooler that I am using? I want to try overclocking more, but I don't want to push the temperatures too high... Also, do you think it is better to have the more powerful fan pushing or pulling? I have the Heatsink aimed towards the top of the case. (horizontal orientation) The temps are slightly cooler when in the horizontal orientation. I have tried both Here are my relevent specs:
core i7 930 @4.004 Ghz @ 1.256v core voltage
prolimatech megahalems rev. B cooled with push/pull setup. (pull fan = 1750rpm, push fan = 1450)
antec 1200 case
sli gtx 260's core 192
1000w psu
asus p6x58d premium mobo
6 gb corasair xms3 1600mhz ram
Also, the fins on the megahalem do not feel hot to the touch even under prime95 testing. Should I be able to feel heat on the fins? (the barely feel warm at all actually) I did NOT try feeling the cooling pipes while the computer was running.... The megahalem seems to have a very secure mounting system so I don't think that is the problem. I put a razor on the bottom of the heatsink to see if it was completely flat and found that it was not. I tried placing thermal paste on the bottom of the heatsink and then put it on top of the cpu to see if the two were completely flush. The cpu was not entirely covered in the thermal paste; therefore, I think the two were not completely touching. Prolimatech specifically states that lapping is a bad idea and can degrade performance. What do you think? Any help you could give would be greatly appreciated. Ambient room temp is about 75 degrees F. (23.9 degrees C)
