This isn't really a shoot-out, but I will be comparing the RVT-9225 to the Arctic Cooling Freezer 7 Pro. I reviewed the AMD version, the Freezer 64 Pro nearly two years ago when it was released. I have bought two since then, and recommended it many times over. In my opinion, it, and its Intel counterpart, are the two best cooler buys on the market (nearly Thermalright performance at half the price or less). The Freezer 7 Pro is very similar to the RVT-9225 (perpendicular configuration, 92mm PWM fan with three heatpipes).

The Freezer 7 Pro was mounted exactly a week prior to this test. The AS5 hasn't cured fully, but it has had some time to cure, so I can probably expect a couple of degrees better than I will see with the RVT-9225. I have always gotten at least 5C better after the 200 or so hours that it takes for AS5 to cure, so keep that in mind.

All testing is done with 74F ambient room temperature (23.33C). I left the Intel QST enabled to keep fan speed down for noise control. As I expected, the Kingwin fan turned about 500rpm faster than the Arctic Cooling fan. During the testing, the AC fan never got much over 1000rpm, and the Kingwin fan stayed well under 1600rpm. Neither fan was significantly audible during the testing. The QST kept my fans always running where they should have been.



First, I checked temps at stock clock, stock voltage. Both coolers hold a respectable 27C.



I had a problem getting the Q6600 to max out. I tried several things, eventually I was running Folding@Home, SuperPi, Prime95 and Everest Stability Test, all at the same time. I still was getting only in the high 90s. Finally, I used the Sandra Burn-in, unchecking all tests except for the CPU Arithmetic Test.

The Arctic Cooling offering held a steady 40C. The Kingwin bounced around quite a bit between 34C and 44C which is common immediately after installing AS5, it averaged 41C.





Next, I overclocked the Q6600 to the clock speed of the next Quad, the Q6700, at 2.66 GHz.

The Freezer 7 Pro maintained a 27C idle temp and 41C load temp. The RVT-9225 managed a 28C idle and a 40C load. I think that the disparity from the stock clock test was due to my room temp climbing up to around 76F, and I had cooled it back down by the time my first overclock test was completed.





Finally, I overclocked the CPU to 2.92 GHz. The Freezer 7 Pro's idle was 29C and load was the same 41C. The Kingwin's idle was 28C, and load once again was 40C.

So, let's conclude this review.
