So you've got your brand spanking new processor, and are looking for some overclocking lovin', you also know you need a heatsink that does the business for you. So you've got two big ones to look at if you just bought a P3 or Athlon. The two that have been causing a stir are both GlobalWin devices. In this roundup we look at the two heatsinks that are creating quite a stir. However which one is better for your bucks. Here are the two contenders : the FKK50 and the VOS32+.
While we have already reviewed the VOS32+, here at UKGamer we simply can't praise this cooler enough. It's huge, the amount of metal you get for #your 35 is quite astounding. This, however isn't a heatsink and fan, it's a complete CPU cooling system. Supplied is a plastic duct, which can fit either a P3 CPU or an Athlon CPU, and a case fan to direct cooler air at the CPU. The whole package works very well.
Then you have the FKK50. This is a much more modest offering from GlobalWin. It doesn't boast any of the extravagant sizes that the VOS32+ does, however it does have something it's bigger brother doesn't have. The fans mounted on the heatsink run at seriously high RPM. When you are talking about two fans running at around 7000 RPM each you are taking serious volumes of air being shifted. This could be a possible explanation if the FKK50 beats the bigger VOS32+ in our tests.
Before we take a more 'in-depth' look at each heatsink and how they performed, here is some info on the test system that we used.
CPU : AMD Athlon 550 (clocked at 550MHz)
Board : Biostar M7MKA
Thermal paste was reapplied every time the heatsink was changed. You can get thermal grease/paste/compound (same thing) from any good computer hardware store, or you can get it at Overclockers.co.uk which is where we got ours from. The thermal paste is not a gimmick, it really does make a difference. The simple explanation for using a heat transfer compound is because it will give you a better contact between the CPU and the heatsink. The metal surface of the heatsink (and to a lesser extent the CPU) is very rough and if you apply some heat compound and rub it away you will be able to see the little bumps you have filled with heat transfer compound. It provides a very good contact. The contact between our FKK50 and the Athlon was so strong it was physically hard to take the heatsink off the CPU and required a screwdriver to lift it.
Conditions were kept as stable as possible, but as usual these tests aren't under perfect conditions. When testing the VOS32+ we found that if we left the window open for a while, the temperature drops. Therefore during the test the windows were firmly shut and the case was closed at all times. We can't take responsibility for gusts of wind that managed to get into the case, but we did check that the results were on par with those reported a minute or two later.
Without further ado lets take a look at the FKK50 first.
