| Thermaltake DuOrb Heatpipe CPU Cooler
|
Installation:
The Thermaltake DuOrb heatpipe CPU cooler was installed in a system with the following components for this review:
» Intel Core 2 Duo E8400 dual core processor
» eVGA NVIDIA nForce 790i Ultra SLI motherboard
» Kingston HyperX 2GB DDR3-1600 Dual Channel Memory Kit
» Two Western Digital Raptor 10,000RPM 36GB 3.5" hard drives
» eVGA GeForce 8800GTS G92 512MB video card
» SAMSUNG 20x DVD Burner with LightScribe
I recently bought a 790i motherboard and E8400 processor, and desperately needed to find a better cooler. With the stock cooler the core temperatures were getting above the 70° Celsius mark, even at stock speed and voltage.
Below is a shot of the 790i motherboard and the E8400 processor installed with Thermaltake's Intel 775 mounting hardware. The 790i series has the CPU socket surrounded by some large heatsinks, making it difficult to pick a large aftermarket cooler. Due to this, the DuOrb wound up only fitting in one orientation, and required a little extra effort.
If you look closely in the image above you can see the mounting hardware is very close to the heatsinks on the motherboard. At first I thought it was going to be a very snug fit, but after placing the DuOrb on the CPU socket I realized I was mistaken. The mounting clip would not fit between the heatsinks when screwed down all the way.
So, I used a black magic marker and colored the area of the mounting clip I needed to grind off to allow the retention bracket to screw all the way down. The images below provide a before and after of the mounting clip in the areas that had to be modified to fit the 790i.
 
The images below are of the part of the bracket that will be positioned next to the tallest heatsink, which is over the northbridge. The metal is soft and only took a minute to grind down both ends.
