Hello guys, I have a Core i7 860 @ stock 2.8 GHz and had it running for a few months using the stock cooler. The stock cooler is awfully awful, it has 0.75" thick aluminium fins, and a "kinda" silent fan. This stock 1156 box cooler was intended for low noise and small cases, I know. But what is the point of sleeping in peace when your CPU is burning at 94°C? This cooler looks like one third of a Pentium D cooler! Come on Intel, either give good coolers, or drop the price and let us take care of the cooling system. I do graphics designing, gaming, video editing and encoding and 3D modeling. And the stock cooler has horrified me countless times when doing anything (with the exception of gaming). At an ambient of 33°C, the CPU cores idled at around 46°C. Maybe thats more likely because of the i7 downclocking feature than the efficiency of the cooler, LOL. Gaming used to hit 60-67°. Prime 95 Large FFTs used to hit around 84°C. 3D rendering using mental ray hit 81-82°C. And the worst nightmare, Linpack x64 pushed it as high as 90°C!! So I dismantled the case, removed the stock cooler and installed Thermaltake SpinQ VT (http://thermaltakeusa.com/Product.aspx?C=1417&ID=1904). This cooler is HUGE, and the stock one looks like a child when put side by side. But what about performance? Let's find out. Installing was painful, I had never installed aftermarket CPU cooler before. So, I had hard time deciding how and how much thermal grease should be applied. I tried spreading a thin layer over the CPU and ran prime 95. Temps jumped near 96 instantly and I shut it down. Removed cooler, cleaned, applied a lot, and booted. This time, prime 95 hit 90C. Something was wrong. Removed cooler, cleaned, applied just one drop at the center, and booted. Finally, it showed acceptable temps around 67°C. I'm not sure if that is 100% perfect, though, but its best I've found, and I can't risk doing it again and messing everything up in some way. I'm satisfied with 67°C, ha ha. After installing this cooler, I ran the old benchmarks again to make a comparison. The CPU cores idled at around 38°C. Prime 95 Large FFT hits 67°C now. That Linpack benchmark hits 71°C. Gaming (Crysis, UT3 mainly) hovers around 42-52°C. Rendering gets 60-63°C and yes, the ambient is still 33°C. I made a comparison below to summarize the things. Please note that the temperatures I have mentioned is the average of the "core" temperatures, not to be confused with "CPU" temperatures. I used realtremp and coretemp to monitor the temperatures. So... are my temps fine? Please feel free to share your opinions on this subject. If you have the same cooler or CPU or both, then please share your own experiences. Thank you. M. A.
