Kingwin RVT-9225: Budget priced cooling results in budget performance

Introduction
In our CPU Cooler review in March, the Noctua NH-U12P emerged as one of the best cooling performers we've tested here at AnandTech. However, at a price point of around $90 with two fans, that performance doesn't come cheap. Today we're going to look at a less expensive alternative, the Kingwin RVT-9225.
KWI Technology Inc., known as Kingwin, sells a number of PC components besides CPU coolers, including power supplies, fans, cables, and so forth. Their CPU cooler line has three recent models supporting modern processors; these are all part of the Revolution line, which consists of the RVT-9225, the RVT-12025, and the RVT-12025D. All of these incorporate "H.D.T." as they term it, Heatpipe Direct Touch, which essentially describes what it is: the heatpipes actually run through the CPU block and have a large contact surface to the CPU.
As we'll see, this is effectively marketing hype and does not provide performance gains over other approaches. The RVT-9225 is the smallest of the bunch, with a 92mm x 25mm fan (hence the name), and retails at Newegg for around $30.

The new king IS the Thermalright IFX-14. Two Ultra120s in a single package.Noya - Wednesday, July 16, 2008 - link
A retail passive cooler will never beat 120mm tower coolers.Mgz - Wednesday, July 16, 2008 - link
the base of the heatsink/heatpipe needs a good lapping, it was in such a terrible shape :(icingdeath88 - Wednesday, July 16, 2008 - link
What's that about the spoiler? Seriously? What purpose could it possibly serve?Bieszczad - Wednesday, July 16, 2008 - link
It is supposed to deflect some airflow down towards the power regulators behind the heatsink. With a cooler that blows air down, the power regulators do get sufficient airflow, but when you use a tower heatsing with a side/front mounted-fan, the MOSFETs do not get enough air and the spoiler is supposed to fix it. Not sure if it works, though, because mine was loose and I ended up taking it off lest it falls out and shorts the motherboard.zebrax2 - Wednesday, July 16, 2008 - link
those results are terriblemmntech - Wednesday, July 16, 2008 - link
First of all, the cooler isn't properly lapped. It looks like somebody took coarse sandpaper over the bottom of it. Could be a bad installation too.strikeback03 - Wednesday, July 16, 2008 - link
Not exactly the reviewers fault that the bottom of the cooler is the way it is. IIRC they have tested all coolers in as-received condition.Clauzii - Thursday, July 17, 2008 - link
With a 'plate' like that, one could mount a Antinov Turbopropeller - probably wouldn't help..Wesley Fink - Wednesday, July 16, 2008 - link
As a policy we don't lap coolers we test at AnandTech. Buyers should not be required to do after-purchase grinding and sanding of a cooler to match our test results. Also the curve on many cooler plates (the better ones normally) is curved (not flat) by design and lapping can actually make performance poorer. Our philosophy is to test the cooler as received from the manufacturer as much as possible.Yes we have lapped a few units and compared performance to the unlapped cooler. We may even comment on those lapped results, but test results for comparison are reported for the cooler as received.
