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.

I blame the push pin mounting. Push pins such enough as it is, and from the looks of it, they put the fan on first, then installed the push pins by wedging a finger between the fan and the pin itself. That is just not good form for mounting a cooler, probably just one of the pins is "locked" in place but not actually in all the way causing uneven pressure and ridiculous temps.flopsie - Monday, July 21, 2008 - link
hmm... i got 2 of these cuz they were 15 bucks, and put on on my dual athlon 64 4200, and one on my core quad 6600. the athlon machine saw the cpu temp drop 9 degrees c, while the intel one only dropped about 3 degrees. it could easily be that those plastic tabs on the intel style mounts just dont supply enough positive pressure.Dark Legion - Saturday, July 19, 2008 - link
Hmm...I see under test configuration that the ASUS silent square pro cooler was supposed to be included in this review, and yet it wasn't. The list in test configuration also seemed to have more coolers than the benchmarks, so I'm sure there were more that were skipped. Can we possibly see the benchmarks for the rest of these coolers?flashbacck - Wednesday, July 16, 2008 - link
Are those ambient noise readings correct? Ambient noise of ~38 db is pretty loud.Bieszczad - Wednesday, July 16, 2008 - link
Well, with the reported temperatures so high, the fan needs to spin really fast to remove the heat, hence the noise.CoreTemp misbehaving? Bad diode on the motherboard and/or processor?
Flaky BIOS?
Anyway, those temp and noise numbers stink.

yeah, but it says ambient noise was measured at 38 db which should be with all systems off, or with only a passive cpu cooler on the setup. Either way, it's too loud.Baked - Wednesday, July 16, 2008 - link
From the charts it looks like the reviewer did a bad installation of the heatsink. It's very common for push pin heatsink to have improper installation, especially if people are too lazy to take out the entire motherboard for installation. I know, I did this with the arctic cooling freezer pro 7. You can't just slap the heatsink into position and push the pins in and call it proper. There's not enough clearance between the mobo and mobo tray for you to do that, and you'll just get the pins bent. You have to take the mobo out, make sure there's enough clearance behind the mobo, set the heatsink in place, and make sure the pins are properly threaded through the mounting holes, locked, and secured. You might need 3 hands for the installation if you're one of those clumpsy people.Even with the poorly finished heatsink surface, the temperature shouldn't but that bad. It's obvious one or more corners of the heatsink is lifted during testing due to improper installation. I suggest the reviewer redo the testing using the proper installation method I mentioned above.

Who knows what went wrong with the testing methodology...but I think we can all conclude that there is no way those numbers are correct. Besides, any heatsink review where the Arctic Cooling Freezer 7 Pro places 2nd place in load cooling temps is automatically suspect.JarredWalton - Wednesday, July 16, 2008 - link
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.biassj - Wednesday, July 16, 2008 - link
Don't confuse this one with it's bigger brother, RVT-12025. Which is basically the same Xigmatek HDT-S1283. 92mm vs 120mm.
