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.

    Load temperatures at stock clock speeds on a dual-core CPU are hardly that demanding. That the Freezer 7 Pro has a higher minimum fan speed could easily account for its placement. Look at the overclocking and scaling charts, and of the tested HSFs the Freezer 7 Pro places in the middle of the pack. Reply

    Don't confuse this one with it's bigger brother, RVT-12025. Which is basically the same Xigmatek HDT-S1283. 92mm vs 120mm. Reply

    This cooler is identical to Xigmatek HDT-S963 that I have, even the typo on the base label is the same. I have mounted the Xigmatek using the Crossbow kit they sell and Arctic Cooling 5 and my temperatures dropped about 7 degrees C when compared to Intel stock cooler. I am running E8400 at rated speed in a cramped case.

    The pushpins are not enough for that cooler, it is actually 70 grams heavier than Intel specifications for the pushpins. The Xigmatek Crossbow will fit on the Kingwin, get the Crossbow and retest, please.

    There are plenty of heavier coolers that use the push pins and get better results than this. If the stated 410g is correct, the stock Intel HSF is heavier than this cooler.

    I'd guess either this cooler is defective or they fill the heatpipes with an insufficient medium.

    They review the identical heatsink sold by Xigmatek. The fans on Kingwin and Xigmatek also have identical specifications. So either Anandtech got a defective unit or the cooler was not mounted properly.

    I'd agree it is probably a defective unit, but it is possible the Kingwin component choices for the design are different. Regardless, Newegg has the Xigmatek unit for $25-$10MIR, so not much point to looking at the Kingwin anyway. Reply

    "Component choices for the design are different"

    I beg do disagree, those heatsinks are identical not only cosmetically, it is the EXACTLY the same cooler, it is just being sold under different brands. No material differences between them.

    And you know this how? Has the actual maker of the unit stated that both are absolutely identical? Reply

    I cannot remember where but I did read somewhere that Kingwin is the actual original maker of these (Xigmatek designed and engineered the cooler), it would not make any sense for them to use better materials for other brands and shoot themselves in the foot by offering an inferior solution.

    Hmmm... Granted, this has only a 92mm fan, but I would have expected better results than this. This looks a lot like the top-rated Xigmatek HDT-S1283 and OCZ Vendetta 2. How was the thermal paste applied? Application of thermal paste on these exposed heatpipe coolers does not follow the same bb-sized, rice-sized, or pea-sized glob in the center of the IHS recommendation that you would use for a normal cooler. As another poster mentioned, the bottom of the heatsink looks pretty rough, and a good lapping might be in order, but I don't think that will make up for these horrible results. I use the Xigmatek mentioned earlier with a 120mm fan and like many others, get superb cooling. (Check out the "Cases and Cooling" forum to see what others say.) Does the 92mm fan make *this* much difference? Or does Kingwin implement the cooler design (or use different materials) in a different way than the Xigmatek or Vendetta? Reply
