I bought a 4870 512mb like 3 weeks ago, worked for a week and i couldnt stand the cooler on it (really isthe worst custom cooler powercolor ever made)as it sounded like a jet engine!. Got a watercooling block, applied it and all was going good (i had done leak test prior to mounting to card), was in the process of booting it but then i noticed that one of the stop caps must have come loose so the o ring didnt fully seal, leaked a fair bit so turned everything off and screwed it back down.
Waited about 10 hours and tried it again after it was dry, no luck no output and i had the 1st led and 3rd led on (starting from the closest to case side panel). Had a look and it appears its the error code for something not correct, i decided to just take the block off and put the old jet engine back on. I put that back in and i got a display! But one major problem.... the fan is not working? Im not sure if its a faulty fan header or the fan, it died so the card gets extremely hot within the minute of booting (i get to windows loaded all fine, then i shut it down).
Any idea on how i could somehow sort this cause its not a standard 3pin fan (well its 3pin but its a tiny connector!). Should i just somehow take the fan out the heatsink and see if i can mount a bigger on on there?. Im not to fussed about the card as i did take it as a "count your losses" and gave up and got this gtx 460 which im happy with now but if i can get it working then i can sell it for probs £30+ and put it towards a new display/SSD.
believe the card is this one http://www.powercolor.com/global/pro...ures.asp?id=79
Cooler looks good, poo in real life haha.
On a side note, does anyone know why my EK light block has a fair bit of black or something forming? It looks like its corroding.... i dont get how thats possible as its been left in its packet and was thoroughly cleaned and well its copper!. Be nice to sell this block aswell .
