Hi guys,I bought a galaxy galcier (with nv silencer) 6800GT last week, they finally delivered my 6pin sli power connector today and when I got the thing I imidiatly installed the gfx in my system and everything. Installed the drivers.. and then checked the temps a bit. It idles @ 50/55 and load 60/65 degrees. I also checked the card feeling for the hot spots while running. and i found these.. They are relaxtively hot on both sides of th pcb.. What can I do to improve the temps of these hotspots and also get the gpu temps a bit down. Since the card will be voltmodded in a while.

Here is a pic of the hotspots:

If the cooler dont cool ram, buy zalman blue alu heatsink and forget rear part of card the voltage mosfers have that black alu cooler on them.

Will a stock amd Heatsink with a aftermarket 80mm fan cool the gpu better than that cooler whats on it now? If so, ill put that on plus buy some heatsinks.

Looking at some pictures of the NV silencer, my first instinct is to suggest you try lapping it for better temps. Looking at a close-up pic at http://www.nvnews.net/reviews/arctic_cooler_nv5_silencer/page2.shtml , it seems that it could really use it.

From there, before you start trying all manners of alternative cooling methods I would probably suggest evaluating the airflow you get around your PCI slots. As a general statement, the PCI area of a motherboard has notably worse air circulation than the rest of the case. If you don't have sufficient ability to move cool air into that area and hot air out then all the after market coolers in the world wouldn't help you cool you GPU. I am personally a proponent of having a seperate fan directly over the PCI area for that purpose.

I can't comment on the AMD cooler, but if you do decide to take a route that has you adding seperate heat sinks onto each RAM module (like those Zalmans suggested above), you'll probably do pretty well with RAM temps... but take off the stupid thermal pads they supply with them and use some thermal epoxy instead as those thermal pads insulate the heat as much as they conduct it.

I tried to fit the sink on the gpu yesterday night but the holes in the pcb wont match the sides of the heatsink so i couldnt fit it propperly...

Well, Im getting a zalman vf-900, I think thats the best I can do atm.

hmm, this thread was interesting to me when you mentioned trying to use an AMD HSF for replacement cooling on the gpu. what exactly do you mean the holes in the PCB didn't match up with the hsf? i was planing on just doing a template on the bottom of the amd heatsink with the stock gpu cooler and do a little drilling and tapping:D

has anyone seen this done? i've done a search here to no avail yet and google hasn't done me right yet either.

I've e-seen it done, but only with Intel and after-market coolers... havn't seen it tried with any AMD ones specifically. I would like to see it done with one of the heatpipe coolers they toss out with their processors now though.

If it helps, someone here did take a zalman 9500 and chop it all chop to heck to make it work...

Yes, it would cool it insanely well, if you could find a way to do it. I remember somebody posted a thread about doing it here a while ago, I think it was like an x800xl, and it idled in the low 30s.

I found a amd heatsink 2 days ago and i wanted to fit it on the gfx with tywraps like the tutorial @ vr-zone. But i found out the sink was too big for the friggin holes in the gfx:( What cpu heatsink is know to fit well on 6800gt's?

One.... Big..... Fan.

120mm x 38mm + 3000rpm = cooled card.

thats similar to what viperjohn did, I would think its better then the stock for sure :)
