I ran a small series of tests on the unit to see how well it performed on both a standard speed system and an overclocked one. The base system consisted of:
- Antec SX1030 Tower Case
- Abit KT7 (non-RAID)
- Thunderbird 1000
- Arctic Silver Thermal Compound
- 256MB PC133 CAS2 SDRAM
- Creative Annihilator2 GTS w/ 32MB
- Sound Blaster Live
- Western Digital 20.5GB @ 7200 rpm
I ran the tests with the processor clocked to 1000MHz and then again at 1100MHz. The overclocking was done by FSB settings to try to create a hotter processor. This gave results that showed how well it performs under both normal and excessive conditions. The testing itself consisted of monitoring the processor temperatures when the system was idle, after a heavy deathmatch of Quake3, and then after a looping of the demo included in 3dMark2001.
Editor's Note: Sorry if this paragraph is getting old, but I am keeping the tests very consistent for all of the heatsinks that I'm testing. This will allow for a future roundup that is completely fair to all the units involved.
The WBK-38 managed to beat out the FOP-38 in all of the overclocked results, but was about .5 - 1.5C off the mark in the stock speed category. So what does this mean? If you are going to overclock your system, then this is a better unit than the older FOP-38 model. It was about 1-2C cooler in the overclocked tests. While this may not seem a lot, it can make a difference in how much you are able to get from your system when it comes time to turn up the juice. More cooling will normally mean more speed, and that's our main goal in overclocking to begin with...isn't it?
While the FOP-38 managed to edge out the WBK-38 in the stock speed tests, the WBK took the cake in the overclocked tests. To be mean to this unit and see if it could withstand even higher stress, I bumped my system up to 1231MHz and ran the tests again. The highest temperature that I could coax out of it was 41.9C in the Quake3 Deathmatch test. Considering that my goal is to keep temps under 50C at all times, this shows just how well this HSF can perform.
There are a few heatsink/fan combinations out there that will beat this model in cooling performance, but not many. And none of them will beat this one out as far as a price/performance ratio. The cooling offered by the WBK-38 is exceptional, and being priced at under $30 USD makes it that much more attractive.
Bottom Line...If you have any intentions of overclocking your system in the future, then it is foolish not to buy yourself a quality HSF. This model is just that...QUALITY. It performs like a champion, and won't leave you wondering what freight train just hit your wallet. You just can't go wrong with this cooler.
