The base of the cooler was flat when checked with a machinist rule but wasn't as smooth as some others on the market.
The installed fan is Spire's 90mm Spider-Fan design that is rated at 2300 RPM with a CFM rating of 25.78 @ 21.0 dBA. When I powered up the fan, I couldn't hear it without putting it close to my ear. One last thing about the fan, it's UV reactive, so that should make the case modders out there happy also.
Installing the DiamondCool was a very easy task. Remove the stock cooler and retaining bracket, clean the CPU and apply the included thermal paste and screw the cooler down evenly. If your motherboard didn't come with a back retaining plate, you'll have to use the one Spire included with the cooler. I used the one that was included because my stock retaining plate was the plastic version and the included plate is metal and offers better support.
Below we have the DiamondCool installed and ready to run. As you can tell, it's not an overly large cooler and I didn't have any clearance problems at all.
Let's move on to take a look at the VertiCool...
