Pros: Go on easy if you follow the directions. I'm running 34C on the gpu and 42C on the gpu diode idle and 38C 49C respectively at load. Much better than the stock at 68C idle and 75C load. I have 3 of these with 3-Way SLI 8800GTX w/split 3 way flow so each card gets fresh cool h2o. Simple installation with included thermal pads and thumb screws. They also match my black 780i mobo and evga gtx black pcb's.

Cons: I'm not sure how you would run a straight thru loop with these cards with the nozzles being positioned as they are. I would imagine your hose would kink but if you went left to right down the line i guess it would be ok. That would be the only con if I were trying to run it straight through. Oh and the fact that the hose connectors are 3/8 if you are running a 1/2 hose you may have to get adaptors. I am running 3/8 so it doesn't matter to me.

Overall Review: Make sure you use the hose clamps included in the kit and tighten the block screw on mounts (not the thumb screws) with a pair of pliers. If you don't you run the risk of the thumbscrew over powering the mount and it popping out on you. No beuno.

Pros: Its a cooling block that fits the 8800GTX. Zalman RMA service and support staff did a great job.

Cons: Terrible machining of the product. Half of the tapped holes where too big for the spring loaded screws and wouldnt stay in place. Got another unit from Zalman via their RMA process but still had the same issue. I actually had to settle for glueing those screws in place.

Overall Review: I also have the Reserator XT from Zalman which I have had problems with as well. So far I cant say I would recommend any of their products to potential buyers.

Pros: It works as intended, keeps my GTX's cool and silent.

Cons: I have a complete Zalman WC set up with the Reserator XT. I connected the Zalman tubing and supplied hose clamps as instructed, but after 2 hours of playing Crysis the hose popped off and voided coolent over the bottom of my case and left a nice blue puddle on my floor. I was lucky the hose spurted the coolant away from the MB. So...after quickly unplugging my machine, I disconnected everthing below the "wet-line" in the case and let it dry over night. The next day I re-connected everything, re-filled the Reserator with coolant AND double-clamped the tubes onto the nozzles using the supplied metal clamps AND plastic "snap-clamps". I was greatly relieved that no damage occurred to my computer. Everything has held together since I installed the plastic snap clamps.

Overall Review: The supplied metal clamps didn't hold the tubes onto the nozzle, you may want to use something that doesn't expand when heated like metal and use plastic snap clamps, or both (the nozzle is long enough for 2 clamps).

Pros: Easy to install and comes with everything you need

Cons: Does not come with instructions on removing the stock cooler but its not hard if you know what you are doing. User manual showed thermal pad installation for 8800 GTS and not 8800GTX but again easy to figure out if you know what you are doing.

Overall Review: Replacing my Tri-SLI rig with 9800 GX2 quad SLI so these babies will be for sale soon

Pros: Very solid build feel and nice performance, keeps my both my 8800GTXs at ~40°C. Slim profile.

Cons: Somewhat tricky to install, it has small threads into aluminium so make sure not to over tighten as they will strip.

Overall Review: It still works fine if one of the bolts is missing.

Pros: Excellent quiet cooling.

Cons: A bit tricky to install. Put the pets outside so they don't interfere.

Overall Review: An Exacto knife or small flathead screwdriver can be useful for removing the plastic covers from the adhesive strips; they are delicate.

Pros: Awesome stuff, these are the best blocks you can buy!

Cons: Nothing.

Overall Review: Best thing you can find to cool a GTX. However, if you're cooling a cpu and this card on the same system, unless it's a radiated system, the heat from the GTX will make your CPU run higher(Reserator 1 cools CPU alone at 20C load, with GTX attached, 45C load). It has everything to do with the heat of the card, nothing else, it is something to take into consideration though.

Pros: Very well made. Goes on easily. Cools effectively.

Cons: Can't find one yet.
