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.

Thermal paste was applied over the entire surface of the CPU, spread to a thin layer. It shouldn't be an application problem, but I will verify when I remove the cooler and take pictures of the surfaces with an article update if I note any problems.As I mentioned in the article, I was also surprised at the performance, and checked the mounting pins, airflow, etc. several times during testing. It may simply be that we received a bad sample. If I discover any issues, I'll update in the next couple of days. Reply

I just bought a Cooler Master Hyper Z600 cooler with 12 heatpipes and it's awesome! I have a feeling it's gonna outperform the ThermalRight Ultra 120 Extreme and maybe even the Noctua NH-U12P as it is HUGE!! I hope it will be reviewed here soon. ReplyImmortalZ - Wednesday, July 16, 2008 - link
The new king IS the Thermalright IFX-14. Two Ultra120s in a single package. ReplyNoya - Wednesday, July 16, 2008 - link
A retail passive cooler will never beat 120mm tower coolers. ReplyMgz - Wednesday, July 16, 2008 - link
the base of the heatsink/heatpipe needs a good lapping, it was in such a terrible shape :( Replyicingdeath88 - Wednesday, July 16, 2008 - link
What's that about the spoiler? Seriously? What purpose could it possibly serve? ReplyBieszczad - 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. Replyzebrax2 - Wednesday, July 16, 2008 - link
those results are terrible Replymmntech - 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. Replystrikeback03 - 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. Reply
