Thanks to MPL for

supplying us with the CAF12 & CBF32!

Introduction

Because videocards become faster and faster every day, it’s almost inevitable that

they also get hotter and hotter; especially when you are a proud member of the

overclocking community (like I am). This heat is the main reason why overclockers

will want to add some additional cooling to their videocard. One way to solve this

heating problem is adding a larger heatsink and fan to your videocard, but the

disadvantage in this setup is the loss of one or sometimes two PCI slots and it also

means the end of your videocard warranty. A much better solution is adding a

cardcooler to your system. This is where the GlobalWIN CAF12s & CBF32s come into

action.

Let’s have a look…

installation.

My First Impressions

CAF12

The GlobalWIN CAF12 uses only one 120mm Innovative fan which pushes around 65CFM

@ 2500RPM. 65CFM!! Impressive, huh! The CAF12 has fan guards on both sides of the

cooler which is very useful; unless you want to eat sliced fingers for dinner this

evening :) Mounting the CAF12 is really a piece of cake thanks to the mounting rail

which allows you to slide the cooler up or down a little to adjust its position. As

soon as it’s attached, the CAF12 hangs rocksolid next to the AGP/PCI slots. The

CAF12 has to be powered by an ordinary molex connector which means that you can kiss

RPM control goodbye on this one. Just one more thing… with its 49Dba, the

Innovative fan isn’t exactly the most silent fan available, but hey, what did you

expect from a fan which delivers almost 65CFM per minut!?

CBF32

The GlobalWIN CBF32 uses two YS Tech fans @ 4200RPM to create a 52CFM air

delivery, which means that each YS Tech fan blows around 26CFM, right? The CBF32 is

also a lot more silent, only 36Dba, than the CAF12. Unlike the CAF12, this CBF32

doesn’t have fan guard on either side; so guys, please be careful when the fans are

doing their work. The CBF32 has the same mounting system as the CAF12. The CBF32′s

fans are powered by two ordinary fan connectors on the motherboard and unlike the

CAF12, this baby supports RPM control on both fans. However, think about this one :

You’ve just bought a Duron 800 that you want to overclock to 1Ghz or more. In order

to do this you bought yourself a nice Superorb with 2 fans. You’ve connected the 2

Superorb fans to the mobo and everything looks just fine… UNTIL… you decide to

buy a GlobalWIN CBF32 which also needs 2 fan connectors on the motherboard.

Conclusion : you’re screwed :)

Testing

System setup

- Asus CUV4X motherboard

- Intel P3-700E @ 933Mhz (7x133MHz)

- 128MB pc133 RAM (cas 2-3-3)

- IBM UDMA/66 7200rpm 20GB

- Creative Geforce DDR @150/350

- Win2k (SP1)

- Directx 8 final + Detonator 6.47 + VIA 4.25a

The Results

I received the following temperature results from the ASUS PC PROBE software. In our

test setup, we stressed the components by performing 3DMark2k loops for about an

hour. Without the CAF12 or CBF32 installed, the CPU temperature went up to a

pretty warm 48C and the case temperature was hovering around 28C. After we left

the fans running for about an hour each, the CAF12 was able to decrease the

CPU temp by 4C to 44C and the case temp by 5C to 23C. The CBF32 performed

almost the same as the CAF12 by decreasing the CPU temp by 3C to 45C and the case

temp by 3C to 25C. In my opinion, these results aren’t bad at all!

By using the CAF12 or CBF32, I was also able to overclock my GeForce DDR’s

memory to a stable 360Mhz (before 350Mhz with only some video sinks installed). A

360Mhz memory speed was the highest stable setting I could get without having errors

in game textures.

CAF12

Good

- Great performance

- Value for money

- No warranty void on videocard

- Doesn’t take a PCI slot

- Solid mounting plate

Bad

- Rather noisy

- You need to remove it to change an AGP/PCI card

- No RPM control

CBF32

Good

- Great performance

- Value for money

- No warranty void on videocard

- Doesn’t take a PCI slot

- Solid mounting plate

- RPM control

- Less noisy than the CAF12

Bad

- No fan guard

- You need to remove it to change an AGP/PCI card

Conclusion

These GlobalWIN coolers look very impressive to me. The CAF12 can easily beat

the competition by using only one 120mm Innovative fan. Both the CAF12 & the CBF32

have their pros and their cons, but they performe almost the same. So I believe it’s

up to you, the customer, to choose the right cooler for the job. One thing is for

sure, you wont be dissapointed with either one of them. So I’d say: if you need a

cardcooler, choose GlobalWIN!
