GPU full cover or block+ramsinks

post #1 of 9
Thread Starter 
Would a GPU block+ramsinks, or a full cover block be better to cool my GPU?

Obviously it's cheaper to get a GPU block and ramsinks over a full cover, but what are the pro's and con's of each?

My card is a BFG 8800GTS 640MB, doesn't get too hot on air, idles around 40° - 45°. Load temps are around 50° - 55°.

Thanks!

Well a full cover block takes the work out of it pretty much. It takes less time to put together and cools all the components on the card. The advantage of using a GPU block + ram sinks is that it's cheaper and will be a few degrees cooler as there is less heat being dumped into your loop.

I would say a block like the Swiftech MCW60 and ramsinks. That would have less restriction than a full cover block.

A full cover would give better memory temps if there is limited air flow over the card.

A GPU block and ramsinks would probably give better GPU temps, while memory temps would still be reasonable, if you have some air flow. Should be easier to mount a GPU only block correctly.

That sounds about right I suppose. The full cover is really expensive so I was just going to buy a block and some ramsinks.

PuffinMyLye, I took all your advice on everything you mentioned a while ago for WC and am gonna buy 90% of it haha.

Thanks guys!

Sounds good, glad I could help. Remember to post pics when you get it up and running. Good Luck.

Here's what my 3870's look like with Swiftech MCW60 blocks and ramsinks. I have a 120mm Delta fan mounted in the front of the case blowing cool air over both cards and sinks.

Note: I cut the ramsinks down where the tubing would contact them to connect to the block so they dont hit.

I have to agree with the some of other poster's in this thread. I went with a custom made water block, plus custom ram heatsinks, due to the fact I can carry them over to the next generation of Video Card. The only change will probably be the mosfet heatsinks (Nvidia always changes the mosfet layout).

Whereas with full coverage blocks, IMO all you really get is "eye candy," that turns into an expensive paperweight, when it comes time to upgrade to the next generation card...

If you look at the pics below, you can see with Viper John's custom water block, the added height allows you to install 1/2" ID x 3/4" OD tubing, no cutting of heatsinks here... I love the industrial look of the Viper blocks.

You can view my cards on his website (same as pics below - 1st ViperFang VI - Black Diablo owner)...

Viper John's Pro Mods

In the tests that Viper John ran, my lower serial # card had the better clock, but he had to match the bios of the slower card, then upped the voltage on the slower card. Even with voltage mod, see the max temps the two cards in SLI ran below:

Torture Test results running (2) evga 8800GTS (G92) in SLI ( w/ViperFang VI - Black Diablo water blocks)

CPU: E8500
CORE: 4901.9 MHz

Bus Speed: 516.0 MHz
Rated FSB: 2064.0


TORTURE TEST RESULTS in SLI:

GPU2:

(like to see a full cover block match these temps)
GPU1: 37 C
GPU2: 38 C
