So, just today I replaced my i5 2500k with an i7 2600k, and I ran into some problems.
After installing the CPU, I tried installing a Zalman CNPS5X
to my P8P67
As it turns out, even though the Zalman fan has Intel 1155 support, I was unable to install the fan, because the second clip was flush against one of the little blue things on the motherboard, right by the cpu. (See pictures in the motherboard link for an idea of what I'm saying)
I had to remove the entire Zalman fan, clean off the CPU with 70% Isopropyl Alcohol and Q-Tips to remove the newly-applied thermal grease, and then once it was dry and clean, I applied the i7's Stock fan, which had thermal grease already applied.
The reason I purchased the 2600k was to improve my video rendering times, but it does not seem to be moving any faster than my 2500k.
What's worse, I began to render a video, only to find out that my under-load temperatures are bouncing back and forth between 69-78 degrees C. It averaged around 72-74C the entire time.
That should not be happening.
With my i5, I had it overclocked to 3.9ghz running on the stock fan, and I didn't go past 70 degrees C.
Overclocking the i7 even slightly sends it to degrees as high as 90C.
When the i5 was running at stock speeds, it was only at 50-55C.
Is this because the thermal grease on the bottom of the stock fan hasn't melted and formed a bond yet? How long does that usually take; I had assumed that running the computer for about 20 minutes was enough to accomplish that.
Did something get screwed up when I removed the after-market fan, and replaced it with the stock fan?
Thanks a million to whoever can help with this, because I'm pretty baffled as to how the temperatures can be this high at stock speeds; and also that I am not seeing anywhere near the increase in video rendering speeds that I was told I would see, by numerous people on both this board, and two other boards.
