    Almost. When you take out the 3 wires, use 2 of them and put them in the old cooler fan connector. Just make sure you have the black one in the same orientation as the original or the fan will spin the wrong way. You'll have an extra, tape it over so it won't touch anything else.
    What I want you to end up with is a 2 pin connector on the new fan.

    All right, hopefully I'll have a chance today to take a shot at it. I'll let you know how it went after I try it out.

    Thanks for the tip, I didn't know those pins could be removed.

    Plugged fan directly into card this time. Light is still red. Nothing's happening. The red light is still in the same place it was before, on the actual card. POST beep and everything, and the fan is running, but nothing else.

    Here's some pictures of where the light is showing up. I don't know what else to attribute this to.

    And this is the cooler on Newegg: http://www.newegg.com/Product/Produc...ero%20l2%20pro

    And the fan IS running, so I know it's plugged in and everything. I put the right color pins in the right spots.

    Don't take this the wrong way. Did you reconnect the monitor cable? Also try pulling the card and reinserting it to make sure it's fully seated. If this doesn't help, I'll have someone else look in here.
    I'm not saying you are incompetent, I've done silly things like forgetting things, many times. I've also forgot to flip the PSU switch on.

    Naw, I know you're not saying I'm incompetent. I'm not offended :P I've done silly things, too.

    Yes, the monitor is connected.
    I've tried re-seating many times, it doesn't work. I have it in as far as it'll go. It's screwed in and secure.
    I've tired plugging it into both DVI slots, still doesn't help.
    I know my PSU is switched on, because the rest of the computer boots just fine.
    I've also tried using a different power cable for the card to see if maybe the cable I was using had a short, but that didn't work either.

    I'm actually really concerned the VRAM coolers on the card may have caused damage or something. The cooler itself comes with a bunch of additional memory heatsinks that glue onto the chips.

    More stupid questions:
    Did you apply thermal paste to the heatsink?

    There should be 4 LEDs on the card, from what I have read. At least the Sapphire 4800 series had 4. There should be numbers next to each LED. If D1601 is lit red it means a "critical temperature fault".

    See post #14
    Sapphire 4850 LED codes?

    The other thing I think of, reading your thread and assuming you have made all the connections and installations correctly, is that the card was critically damaged when the original fan failed. I know that is not what you want to hear, but it remains a possibility regardless.

    And I have a WAG:
    Remove all of the installed RAM from the system and try booting with just one stick in the first RAM slot.
    And for good measure you could also perform a Clear CMOS too.

    Sounds far fetched but I have read posts where these actions have cleared the red LED!

    Thermal paste came pre-applied on the heatsink, and I didn't touch it or remove it. I did clear off the previous thermal paste first before putting the new heatsink on.

    Right after my other fan failed, my card was definitely still functioning just fine. I had run it once or twice to check the old fan (when it was still on the old heatsink) and the card would boot up and work, even with the failed fan in it, and I shut the PC off before the card could get too hot, just so it wouldn't damage it. Is it possible for it to completely die while it wasn't connected to the motherboard or being used? I imagine it could be possible, but was there something I might have done wrong?

    When I have time I'll check the light and see what number the LED is and get back to you ASAP.

    Looks like it's D4000.

    And it looks like this person had the exact same problem as me, the very same cooler I have:

    Just a though. Could the red light be on because the card no longer picks up the rpm's with a two wire connection. Their for the card thinks the fan isn't working. Because of that the video card is shutting it self down.

    If all else fails with this cooler, I can try putting the old one back on. I had purchased a new fan and stuck it on there, and it's a 2-pin, but the plug didn't fit the connector, so I bought the new heatsink instead, figuring it might help with temperatures too in the long run. But now that I know I can pull the wires out of a plug and put them in another one, I can try that with the fan and see if it's the cooler or not.

    The only problem with that would be, I wouldn't be able to re-attach the small memory heatsinks. If nothing else helps I'll try the old heatsink with the new fan on it. It would be nice if this cooler worked out though. Cost 35 bucks to order it.
