Zalman VF900-Cu

I would of posted this in the ATI graphics section but hopefully Asmoday will reply /w his results on his 7800GTX.

Finally a quiet solution for the x1900xtx.

Yes, I know about the Accelero X2. However, with my DFI MB it cooks the chipset.

Stock temps 49c Idle 90c Load.

VF900-Cu

39c Idle 79c Load

Which I think is pretty good considering how quiet it is. I have it turned all the way up, and it's just a very slight hum. Probably about 20-22db. Hopefully temps will down a bit when the AS5 sets up.

wow you weren't kidding how hot those x1900's run. Do you know if it uses the same fan as the VF700s did?

Necrosis · Apr 6, 2006, 05:25 AM

Honestly I don't have a clue. Asmoday had one of those at one time, so he'd know for sure.

I'm not completly sure if it uses the exact same fan. But It do look the same; it's a 80x80x15 fan that operates at 2400 +/- 10% at 12v (mine spins at approx 2600rpm at full blast.

I didn't bother to do any extended checking for the highest load temps with the stock Asus cooler, but it was in the 70's if I recall it correctly. Now with the AS5'd VF900 it maxes out after about an hour running rthdribl @ 52-53°C.
And it wasn't too expensive locally here in Sweden, I picked it up for 295 Swedish (38.80$ USD).

I'll definitely pick a VF900 for my upcoming 7900 (if replacing the original). It's well thought out and the Zalman manufacturing quality makes for a safer mounting than for instance the Arctic Cooling's, though I haven't seen the new Accelero first hand.

Not a chance its that quiet. All the way up it'd be comparable to the VF700 I'd guess and mine on full load is at least 34 dB, still quiet compared to my 56 dB tornado but 20 is REALLY low, I think its 20 - 21 dB When its on 5v mode (or ~35%)

Asmoday · Apr 6, 2006, 02:44 PM

According to Zalman the noise levels are:

1250rpm 18.5dB +/- 10%

2400rpm 25dB +/- 10%

H3X4D3C1M4L · Apr 6, 2006, 02:50 PM

Guess the VF700's have a faster fan? I think its 2600 RPM. Probably a different design too.

Either case 20 at full load is still hard to believe for something that has to keep an X1900XTX cool.

Asmoday · Apr 6, 2006, 03:11 PM

Actually my bet would be that it's between 25-30dB at full blast, especially mine anyway since it runs at approx. 2600rpm at 12v.

Necrosis · Apr 6, 2006, 05:27 PM

Like I said "Probably" it was my best guess.

Speaking of keeping a x1900xtx cool, at the lowest setting temps jumped 2c on idle & load.

Mike which Fan header do you have yours plugged in to? I have mine on 4, and need to figure out how to make MBM read it.

Now I can hear my CPU fan speed up, and slow down under load. I'll be taking care of the problem soon /w a Noctua NH-U12.

I have it at fan header 2 the PWM IC fan header, it reports the speeds in the bios.
