Anyone got an XFX 7800GT Extreme LED with working fan speed control?

    I've been putting up with this for a couple of months now, hoping for a fix. I've finally got some time off work and I'm hoping to get it sorted out.

    I bought the above card from OcUK on the 24th of December. It works fine, but the fan speed is set at 100% all of the time. 7 different drivers - no change. Clean installation of WinXP on a spare HDD - no change. Rivatuner and a couple of similar programs - no change.

    I have come to think that this particular model does not have fan speed control at all. The fan and the LEDs are powered from the same power header on the card, over the same wires. The LEDs require a constant 12V. So how could the fan speed be varied?

    I should have bought a non-LED version, but (a) OcUK didn't stock a non-LED Extreme version when I bought mine and (b) I didn't know there was a problem then.

    I phoned OcUK support today and OcUK will replace the card, no problem. However, they'll only replace it with another XFX 7800GT Extreme LED Edition.

    So...two questions:

    i) Are all XFX 7800GT Extreme LED Editions the UDER or UDE7 models? Or is there a UDF7 model of this card? UDF7 cards seems to work as specified, with a few exceptions.

    ii) Is there such a thing as an XFX 7800GT Extreme LED Edition with fan speed control? In other words, might I get lucky if I do an RMA through OcUK?

    Ooh, that's the first worker I've heard of, on 4 different forums.

    If it's my PC, it's several hundred others at least. Some people have tried the same card in 5 different PCs (in a shop).

    To confirm: You have a UDER and LED edition and your fan speed definitely varies?

    There are problems with some or one revision of the card, it's not your system that is producing the error.

    I don't know which version is good and which isn't, I think there is also a XFX forum and there might be more info there.

    I have no problem as I installed a Zalman VF700-Cu before installing the card in my computer and that doesn't use the onboard header for power.

    I've been using the XFX forums for some while and there is a lot of info there. Especially in the 20-odd page on the issue that XFX deleted.

    The problem is with the UDE revisions. UDE3, UDE7 and UDER. My particular problem is that OcUK will only replace my faulty card with one of exactly the same model. I'm willing to take a card that's £50 cheaper than the one I bought, but no go. The UDF7 (no LEDs, plain PCB) rather than the UDER (black PCB, LEDs).

    The one you have is faulty so exchange it for a new one anyway, the worst that can happen is you get another faulty one, in that case maybe consider getting a Zalman cooler that runs off a molex.

    I had one of these where the fan was on 100% all of the time - I successfully RMA'ed it as it is a recognised issue.

    Did you RMA it through OcUK or through XFX? Did you receive a UDF or UDE model in exchange?
