X1900XT IceQ3 Cooler fit a 4850?

[ArgentumX]

Wishful thinking here, I have a HIS X1900XT IceQ3 that bit the bullet last week :mad:. I bought a Asus HD 4850 to replace it. Does anybody know if the IceQ3 cooler from the X1900XT will fit the 4850? I really want a dual slot cooler that expels the air out the back of the case instead of recirculating it in the case. Plus it would be a shame to toss such a nice cooler.

If not, does anyone know of a cooler that has a similar configuration that fits the 4850?

If the mounting pins are the same as the, 3870, 8800gt, and the base heatsink contacts properly with the gpu, than yes it might...the 4850 and 4870 have mounting holes, very similar to that of the previous generation and a few nvidia cards.

Ok so I took apart the X1900xt and the mounting holes for the cooler line up on the hd4850. Everything looks good, hopefully the gpu is the same height/clearance so the cooler makes good contact. The last issue is the fan header on the 4850 is 4 pin. The fan on the IceQ3 has a 3 pin connection. If I plug in the 3 pin into the 4 pin header will it work? Also, will the RPM of the fan be controlled by the card or will it be going full tilt?

It would be a lot easier to connect the 3pin fan connection to an adapter that hooks up with a standard computer power 4pin connection from the computer's power supply.

Another option is a nearby 3pin fan connection on your motherboard.

The fan should go full tilt if you plug into the 4-pin connector on the card, but we don't know the power requirements of the stock fan, the IceQ3 fan, or what that 4-pin fan header is rated at. You might blow out a circuit. I wouldn't risk it.

[ArgentumX]

Hmmmm, well I wouldn't want the fan going full tilt (way to loud) or risk blowing a circuit. That HD4850 is toasting my NB and my Q6600 because of the heat coming from the back of the card and there are no dual slot solutions that exhausts the heat out of the back of the case :bang head

Have you adjusted the fan speed on the 4850? How is your case airflow?

I'd just use a mobo fan header and use your mobo BIOS or software to control the fan speed. Unless you have a fan controller in your PC.

[ArgentumX]

The case flow is good, I have the system in a P182. I don't want to ramp up the fan speed in the 4850, it gets too loud (have the computer in my bedroom). All the mobo headers are 4 pin as well (Asus P5Q Pro). Would the BIOS still be able to control the fan with a 3 pin connection?

[IWasHungry]

If you plug the 3pin fan into the motherboard, some BIOSes allow fan speed control but not many. Your best bet is to attach/solder a resistor in series with the fan if you really don't want the fan running at 100% speed, because currently the 4850 doesn't have any software that can control the fan speed (Unless it's an ASUS and you use the Doctor-whatever software that it comes with). I know that's not the answer you were looking for but it's all I can think of.

[jason4207]

I'm guessing the mobo fan headers will still allow fan control w/o the PWM line, but I'm not positive. Perhaps there is a BIOS setting to choose b/n PWM and traditional fans.

My P5K-Premium allows some fan control (Abit is better). I have my gfx card fan plugged into the mobo fan header. In the BIOS I used the Smart Fan feature. It uses the NB temp to regulate the fans and I have it set up, so that it runs 70% until the NB gets over 43*C which is perfect for me. When I game the NB does heat up, and my fan ramps up appropriately. An indirect approach that works quite nicely!

watch you dont blow the card with the fan connector

I'm not sure what would happen if the 12V pin and ground pin connections on the video card shorted each other, but I think it would be best if we didn't find out lol.

if you really want to get the 4 pin header to work than you need a dmm, to check the pins to see which is ground, positive etc, or look at the cable, or you could possibly, modify the stock fan so that you could integrate it some how into the iceq. The last thing you could do is probbly rig up a fan controller to the iceq.

Well, you could just take the IceQ3 and find out which wires are what on the cable and cut the connector off, then do the same on the 4850 stock heatsink.
