VF700 on an ATI X800-XL

Hello.

Can the ATI X800-XL control the speed of a Zalman VF700 just like it controls its stock fan?

I doubt it. The fan from the vf700 has to connect to the mobo, not the video card. I am using a fanmate II to control my vf700 @5v. It's very quiet.

It's possible to change VF700 fan mount to connect to graphic card directly. I did it with my Sapphire X800XL. Fan speed can be controlled by stock firmware. If you are not happy with it, ATI Tray Tool can control fan speed. and it spins depend on GPU temperature. I feel a bit safe compare to manual knob.

Default fan speed is a bit high, 50% when idle (<50C). I changed it to 20% when idle. Here my setting using ATT.

Interesting. How well does the VF700 fan respond to PWM? (i.e. any clicking noises etc.)

How?

Hi I was wondering how you were able to change the fan on the VF700? I bought the VF700cu recently and would like to connect it to my video card directly to use the temp and fan control options. Also where can i puchase this fan? thx.

Was it difficult to pull the 2-pin housing out of the X800XL? I want to do the same to my 7800GT but I'm worried that I might break a pin or two by applying too much pressure with pliers.

Thankyou

for the pictures... I have a 700 coming in the mail, and I was curious myself whether I could attach it directly to the card and control the fan via ATT. My fears are now assuaged, and I'll be making that mod when I install the unit.

Thankyou,

TAK

mission successful...

replaced the stock heatsink with the zalman unit, and attached the fan to the onboard fan header. Point of note... the wiring on my zalman, did NOT match the wiring of the stock fan.. I had to pull the wires out of the 3 pin block, and rearrange them in the correct order, before reinserting.

Pulling the socket from the card was similarly easy, but be very gentle when doing it.. you can pry it up easily with a small jewelers screwdriver, for instance... but if you break those pins off, you'll be attaching your zalman the old-fashioned way. Just gently work it up until you can slip the tip underneath the plastic, and go from there.

Dropped my idle temps 12-15c, and loaded temps by 30c or so...

needless to say, the stock heatsink/fan is a real piece of .. err.. ."work"... to put it politely.

You'd think the sapphire would have used a standard 3-pin layout for the fan header. *shrugs*

TAK

*edited note* the temp drops are from the stock config... I saved 10-15 loaded temp, from after I repasted the stock fan earlier this week.

aka, stock fan, 80c+ loaded temp, stock fan repasted, 65c+ loaded temp.. and now, the zalman, with a load temp of no more than 55c, and usually closer to 50c.. not sure what's causing it to fluctuate.. system temp staying fairly even over the same time frame.

awesome, worked for me

awesome post guys did what u guys said and worked out fine. removed fan mount with small jewelry screwdriver switched the wiring around to fit the all in wonder x800t default wire setting set the fan speeds with ati tool. so far everything working temps are lower than stock and 100x quieter.

Is there an Nvidia equivalent of ATi Tool, especially in the area of automatic fan control?

I have an ATI branded x800xl. It appears to have a second fan header on it, has anyone mounted a vf700 on the stock ATI board?

Yes, there is. Wit it you can controll the fan speed for some nV cards, but maybe you need newer drivers (77.77 and above).

It is the Rivatuner...

Works for my with my Leadtek 6800GT.

BR!

Correct me if im wrong, but i think i read on the ATItool page that the most recent version also supports nVidia cards.

Help needed

I connected the VF700 to an ATI X800-XL.

The fan header is different so I made an adaptor connecting the fan's red, black and white wires to the corresponding ones on the card.
Red and Black wires' positions on the headers are crossed.

However, when I connect them that way and power the computer on, the fan does not turn at all.

Is that normal?

I tried disconnecting the White wire, mo change.

The fan seems to work OK (at full speed) if I connect it to the motherboard instead.

I did not test it under load since I didn't even install an OS on the drive yet (I just assembling the hardware parts) and I am a bit nervous that I may damage the card while installing and testing.

Please advise.

Thank you,
Alex.
