while this card is an ATI card, the issues im haveing are more related to the high temp it runs, the core right now is sitting at 65°c idle, havent ran any 3d yet, i know the seconed i do, it will bounce clear to 80°c the fan kick in to high somewhere around 70-75°c,

the card

(hopeing the url wors for ya)

the trouble is, if the card is hot enought for the fan to kick in, its already artifacting in games, it will artifact for about 20,25 min, then vpu recover will kick in, it will only kick in once, and then game fine for hours, artifacts and all.

now, if you look at the heat sink desgin its a 2 part desgin. The part that covers the core is copper, while the part that covers the ram is ALU. also the pads they used to bridge the gap are about 3/16ths of an inch thick (about 3mm) now, if i remeber correctly, this is not a good thing, to have so much thermal material. the other issue is that the core runs so hot, and there is almost no air flow to the alu parts of the cooler. the copper and alu are joined by a few screws so there is thermal transfer going on between the 2 pieces, but i dont think its transfering in the way they ment it to transefer.

im thinking that the core might be serving to heat up the ram more than it is helping keep it cool.

Now my question is, do you think i could get away with running no ram cooler on this card? normally when people ask this question to me i reply -if they put a cooler on it, then it needs it- but you can see why i think this may be a littel different. more so because of the lak of air flow. i fully plan on water cooling this card at a later date (ala when i have money) but in the mean time i need to find a way to get the ram cooler.

i suppose the question should be, are there any other 1000mhz gddr3 cards out there that come stock without coolers on the ram? if so, i might be able to get away with removeing the alu piece.

thanks for your help
 
If the card is not functioning properly at rated speeds, then why wouldn't you RMA it? Seems to make more sense to try that than to go removing a heatsink that you yourself said probably wouldn't be there if it wasn't needed (and incidentally voiding your warranty in the process). It's possible that you just got a sub-standard card, and would surely suck to discover this after you modified it.



 
The X1800GTO cooler was known to be pretty bad. Instead of removing the RAM cooler, you may want to look into getting another cooler for your card.
 
A different cooler is all you need. I have an x1800xl and use a Zalman VF700-AlCu cooler. It fits well, and comes with ram heatsinks. No problems with artifacts or anything.
