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.

With a 'plate' like that, one could mount a Antinov Turbopropeller - probably wouldn't help.. ReplyWesley 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. Reply

There must be sth wrong with the installation. I have seen many users report much lower temperature which is comparable with TRUE. I suspect it's because of TIM apply method. HDT needs different TIM apply method to take advantage of the HDT concept. ReplyBieszczad - Wednesday, July 16, 2008 - link
Could you point me to some instructions how to apply the paste in a HDT cooler setup? The cooler booklet was not clear on this matter. Thank you. ReplyBieszczad - Wednesday, July 16, 2008 - link
