So I was bored and saw my old stock Sapphire X1900XTX OEM Heatsink & Fan sitting by me and decided just to take it a part and see what makes it different from my NV5R3's.
First off, the fan on the stock ATI cooler is of course smaller and, therefore, louder. Secondly, the ATI's fan is not on a level airway like the Silencer. Instead, the fan has an opening beneath it which the air gets pulled up from and expelled through its exhaust (the rear of the case). The Silencer is much more effecient with its airflow since it is constantly pushing air through with a larger, more CMF fan rather than pulling it across and upwards with a smaller, less CMF fan. This is one of the major reasons I think the stock coolers got some higher temperatures.
However, when I took off the white plastic shell I was very suprised. Turns out the stock heatsink has two sizable heatpipes running under its fins.:Q I then disconnected it the grey, plastic base, (please note: anything that is grey, white, red, and clear on the unit is ALL plastic) and found out that they are not very visable. On the underside of the copper heatsink there is the exploded square which, when the unit is completely assembled, protrudes out from the otherwise flat and dense base. This exploded square is the only copper part you see when you initially remove your stock HSF from your PCB. Normally it is surrounded by the grey plastic HSF base.
As you can guess, I started thinking of a way to either improve the HSF or use its double heatpipe copper base to make another. One problem though is that because the GPU exploded square sticks out from the rest of the flat copper base, it would be difficult to get a flush mount without using the grey, plastic HSF base. The grey, plastic HSF just levels the copper unit to allow the flush mount.
If any of you get confused with what I'm saying, just take your stock heatsink apart if your not using it and you'll see what I mean. I'm not generally a modder, even though I've got a Thermalright HR-05 Chipset cooler on my DFI NF4 Expert with a dual slot cooling for my GPU, I don't have much experience with modding most other things, so I think I try something just for fun. Besides, my water cooling stuff is coming in the mail. So, modders, if you want to see if you can transform the stock HSF into some thing that may beat the Zalman VF-900, which is what I'm trying to do, then feel free to post any suggestions. As for me, I wish I had a digital camera so I could show some progress and samples.
UPDATE: OMFG! I've got the hot red head on the white covering too? The wierd Chrome-cyborg looking chick was just a sticker? Weird, but okay.
