4 out of 5 eggsEVGA 8800GT SC (G92)

Pros: Very nice craftsmanship. Dropped idle and load temperatures by 20-30C depending on my systems fan speed and CPU overclocking. Yes, it removed that loud fan that is on these single slot cards. Price is good compared to others brands. Some extra parts.

Cons: I removed one egg for the following reasons; 1) Manual does not explain old fan removal and GPU, RAM, FET cleanup. 2) Zalman block connections have a smaller ID (8mm vs 10mm). Compensated by getting SS Clamps and clear silicon for connections. No Leaks. 3) Someone indicated that the threaded barbs are smaller than the tapped holes and they do seem loose fitting, countered by using Red Loctite so I did not feel the urge to crank down and possibly strip them out. 4) The thermal pads have plastic on both sides (not easily noticeable, one side the plastic is harder to remove, use X-acto knife or a small flathead screwdriver), diamond pattern toward water block (start with the only odd shape piece and you will see why). Also, the thermal pad for the FET area is to skinny (look at old fan you just took off). I removed some thermal material from the old fan (two nice rectangles) and strategy placed it on the water block to cover the two small FETs missed at the very edge of the water block.

Other Thoughts: Used in a PC3-726 Koolance system. Purchased Zalman tubing, but was too small ID for the Koolance (10mm) system. Don’t forget to turn screws down one turn at a time as indicated in the manual. One person indicated he snapping his board, might not have followed this instruction or had a tolerance/obstruction issue. Under load this card would hit 93C and when it was dusty 101C. Wow, felt I needed to do something.

3 out of 5 eggsdoes NOT fit G92

Pros: solid, thin.

Cons: does NOT fit the G92 version 8800GTS.

Other Thoughts: fittings that come mounted on this are for SMALLER than 3/8OD / 10mm hose and works with zalman 8mm kit's and hoses. for a custom setup u will need to scrounge and find larger fittings to work with normal 3/8 hose or it WILL leak. u can try over-squezing hose with a worm clamp, but will very likely leak and definatly look ghetto.
hooked this up to a 8mm hose/pump to leak check it and it leaked slow at first, i re-mounted fitting with loktite and that fixed it.

4 out of 5 eggsDid work good!

Pros: Lowered my 8800gts greatly, very heavy and no larger than the stock heat sink and fan that was mounted to it.

Cons: Had a problem with one of the fittings leaking into my psu of course that went up in a blaze of glory. Sent two messages asking how to get new fittings to Zalman three weeks ago today is 9/14 and i still have heard nothing form them. So i guess this will be a pricey paper weight until i can figure something out.

Other Thoughts: The fittings are smaller than 3/8 so metal pipe clamps must be used.

5 out of 5 eggsSolid Product

Pros: Keeps my BFG OC 8600GTS 640MB around 50C from 66C under load, about 40C and lower at idle. I couldn't even touch my stock heatsink it was so hot, but with this I can.
Looks great, its very solid, very fun to install.

Cons: none

5 out of 5 eggsWARNING! Doesn't fit G92 revision cards!

Pros: Want to buy one for the 8800GTS (G92) but...

Cons: this one doesn't fit the G92 revision...only fits the older 8000GTS cards.

Other Thoughts: Zalman lists the proper part on their site for the G92 revision card as P/N "ZM-GWB8800GT/GTS (G92)". It appears, as of today, that this part is not carried by Newegg.

5 out of 5 eggsExcellent Performance

Pros: Great performance. Good price for "full coverage" block. Good fit and finish.

Cons: Hose clamps and PVC washers missing from parts bag. They did provide extras of most other small parts.

Other Thoughts: Added a second EVGA 8800GTS. Case and motherboard configuration resulted in poor air flow. With stock air Cooler Idled at 62 went to 88 under full load. Used some parts I had around the house with this block. Now Idles at 38 and Highest temp I've seen was 46 while playing Crysis. Other GPU was at 76 with stock air cooler. Ordered a second block today.

2 out of 5 eggsZalman wooes

Pros: This thing is heavy, but thin much smalller than the heat sink and fan that comes with the 8800 gts.

Cons: Removed my 8800 gts got it all apart and greased up. Quess what it didn't come with the parts bag shown here, NOTHING! The graese i already had but no screws, fittings or anything so i had to put it back together. I was going too add it in with my Nautilus 500 and an extra radiator. Please not a reflection on Newegg bacause they have been GREAT.ZALMAN I NEED THE PARTS BAG FOR YOUR ZM-GWB8800 GTS SO I CAN FINISH THIS.

Other Thoughts: ZALMAN I NEED THE PARTS BAG FOR YOUR ZM-GWB8800 GTS SO I CAN FINISH THIS.
