im going to install the koolance GPU block on my BFG 5900NU. Ive heard alot of people screw up there video cards installing gpu blocks on them. i know i have to take off the stock HS. is this easy to take off, how do i go about doing this. and when i take it off would i need to buy other memory coolers for the memory because the watercooler is only on the gpu. and how much thermal goop should i put on the gpu. sorry for so many questions:D

Koolance's GPU instructions


Artic Silver's 'thermal goop' instructions

Koolance GPU-180 coolers come with 8 memory heat sinks, they don't really do squat but feel free to put them on if it makes you sleep better.

Don't worry I'm not gonna flame you for not spending 2 minutes searching the manufacturer's websites for instructions....

so would it be fine just leaving no cooling for the memory.

Depends on who you ask. Many say ramsinks are just for show, many think they are worth it and provide increased performance. However, neither side has evidence to support their theories/arguements. So therefore, it's still a matter of opinion.

I wish someone would do a significant comparison to finally put this beast to rest.

Well it sure helps if you get some mega heatsinks on the RAM :D The problem is that they are usually so tiny it don´t make much difference in surface area.
 
Ramsinks can help but the bottom line is that a memory OC may be limited by a single chip that is not heat limited to a significant degree. I have used them on two 9800 Pros and in one case there was a significant increase in OC (over 20 MHz) and another time there was only a 5 MHz increase.

The bottom line is that if you buy some and stick them on with good thermal tape, you're not going to hurt anything and you might get a higher OC. You have nothing to lose but the money. Also, look on eBay for a good deal on some no-name bga ramsinks.

Hmmm...I believe in the finger test. I have never felt the ram chips on my ATi 9600 Pro even get faintly warm. However, if you are going for the max it pays to cover all bases. Skip the thermal tape and glue the sinks to the board. Video cards are pretty much of little value 2 years after they are made and besides you will probably end up selling it to someone who would appreciate the extra work on your part.
 
Man if I touch the ramsinks on my 9800 pro I get a little imprint on my finger - those things get absurdly hot. I have them overlocked quite a bit, and they're very inexpensive to add on there. The way I see it, any extra metal on top of something hot that can pull it away from the chip will help in some way. Once the sinks get saturated with heat, however, it won't help as much - but that's why good airflow in the case is important.

After reading the above, I'm not sure if that was really helpful or not... But the moral of the story is spending an extra 5 bucks or whatever is completly worth the added peace-of-mind.
 
yah ill think ill take the safe road and get some ramsinks. which are really good ones, anything on new egg preferebly. as u guys said the koolance comes with some but there crap.
 
I'm going to be buying the gpu cooler for my asus 9800xt and was wondering if I should take the heatsink off the backside of the card and put different coolers on it. The heatsink on the back side of the 9800xt takes up almost half the card; does it take heat away from anything else besides the ram?

I don't have one myself, nor have I ever seen one so I don't know first hand - but it seems like that would work even better than the individual ramsinks because of the huge surface area. It may also pull some heat away from the back of the card where the core is, as that usually also gets pretty warm.

Like I said I haven't actually seen one myself, but I would leave it on if possible.
