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

Cooling at Stock Speed
Performance at stock speed (2.93GHz) with the RVT-9225 is exactly as measured with the Intel retail unit. While the stock unit is quite decent, we expected to see a small improvement here. However, it's under load conditions that an upgraded heatsink/fan unit should make a big difference. Load conditions are measured through looping the Far Cry River demo and logging temperature results. The highest sustained temperature is recorded.
Once again, the performance of the RVT-9225 is almost exactly that of the Intel unit. Unless it can distance itself in some manner, the RVT-9225 will clearly lose to the "free" cooler.

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.

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.Bieszczad - Wednesday, July 16, 2008 - link
"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?Bieszczad - Wednesday, July 16, 2008 - link
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.mikemcc - Wednesday, July 16, 2008 - link
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?Matt Campbell - Wednesday, July 16, 2008 - link
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.

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.
