Monster fan, but has it bitten off too much?
Product: GlobalWin VOS32+
#Price: #34.00 from OCUK and 34.50 from CPU-OC (all prices are UK Pounds and include VAT)
Available from: CPU-Overclockers and Overclockers.co.uk

The GlobalWin VOS32+ heatsink and fans. One of the biggest heatsinks on sale in the market. The sheer size of the heatsink dwarfs most of the others on the market, with the exception of the FKK50. However does this justify the high price? We find out.

You get quite a bit for your money. The whole kit comes in two boxes, one which has the heatsink and fan, and the other which contains the retainers/metal clips, case fan and ducting, along with instructions. This is a versatile heatsink. It can be fitted onto Pentium IIs, Pentium IIIs and Athlons. The system I tested the VOS32+ was on my Athlon.

Installation is not as easy as Socket 7/370 heatsinks. I found it hard to clip on the metal clips without taking both fans that were screwed about it off. There was a good bond between the heatsink and the CPU, and applying the thermal paste that was supplied helps the conduction of heat further. Note : The Athlon used did not have it's back plate removed.

So the installation of the heatsink is over, however you have another fan to attend to. The case fan that is supplied is a very nice one. There is some confusion, whether the fan should blow in cool air to the CPU, or take out hot air. So I tried both. The ducting looks at first to be more of a gimmick rather than something useful. I had problems to start off, with the ducting aligning with the space in my case, after much fiddling it was working to an acceptable standard.

This heatsink is huge, the fans on top of the 'sink make it even longer. All in all, the whole package is over 7cm thick. This means that your Asus K7M. The board in our reference system, was the Biostar M7MKA which was able to cope with the space needed. However the power duplicator was needed to be used, since there are only two fan power outputs available on the motherboard.

When you are looking at a cooler of this sort of size, you need some big fans. GlobalWin hasn't disappointed here. The fans are big, very big. To be exact these are the Y.S.Tech 60mm fans, which has been used before in other GlobalWin coolers. When you take a closer look at the fans they are not as impressive as first thoughts might indicate. They run at around 4000 RPM, which is not very high in this day and age. When compared to the FKK50's fans which run at ~6200 RPM it makes the VOS32's fans seem like a Robin Reliant. However the size of the fan means that even at this relatively low RPM, it shifts quite a volume of air. The fans together move 27.2CFM, which isn't far behind that of the FKK50.

Once the fan is installed and everything is working dilly dandy you can see how this monster compares to your old heatsink. The results that we got are for the system that we had, and similar results might not be generated on your system. For your reference the system used here is :

AMD Athlon 550 (clocked at 550 MHz)
Biostar M7MKA motherboard
Procase YCC-802 (system case)

These results are when the case fan was sucking hot air out of the case.

After 6 hours : 37C
After 12 hours : 40C
After 18 hours : 40/41C
After 24 hours : 40/41C

Then I turned the heatsink around so that it blew colder air into the CPU, and I also reapplied the thermal paste, the results where slightly different.

After 6 hours : 32C
After 12 hours : 34C
After 18 hours : 35C
After 24 hours : 35C

You can see that there is a clear difference with when the case fan (that is supplied) blows cooler into the CPU rather than sucking the warm air away from it.

Conclusions

This heatsink and fan combo is huge. There is no doubt about that. It's cooling powers are pretty damn decent too, but you have to look at the whole deal a lot closer. It costs nearly 35 quid, and that is quite a bit of dosh for a cooler. There are many out there in the market which does the job for a lot less. For example the FKK50 is prices at around 22 pounds from any overclocking outlet, and is a pretty decent cooling rig. However, for your money you certainly do get a lot of kit. Two huge cpu fans and one case fan as well as a huge lump of metal. If you want the ultimate air cooling at the moment, you will want this. If you don't require a cooler that gives you high performance, (not everyone has an overclocked cpu, lets face it) then you wouldn't go very wrong by getting a vek32 (if you are on an Asus motherboard) or a FKK50 (for most other motherboards). This is one mean cooling machine and we can't take that away from it.
