Pros: Exceptional cooling, 6 heat pipes vs. 2 (based on Nvidia reference design), extension of cooler past edge of video card more than likely improves cooling by forcing hot air into the upper region of the case to be taken out by the case exhaust fans (as opposed to other designs that force hot air back onto the GPU), TIM pads for the RAM sinks are the best pads I've ever seen to be bundled with a GPU cooler. The pads appear to be thick phase-change pads that stick very well (as opposed to the normal double-stick "Scotch tape-type" TIM pads seen on most other RAM heatsinks; that may or may not fall off and don't provide an efficient interface).

Cons: Extends approx 1 3/8" past outer edge of video card (could also be a pro), heavy (with fan attached), quirky fan installation, precludes SLI setup (takes up three slots), and depending on your point of point of view, it's ugly.

Overall Review: With an extremely limited selection of after-market GPU coolers available for the 8800 series, I decided to take a chance with this one. It's big, ugly, and takes up 3 slots. But man, does it cool (compared to stock)!!! I logged my 8800 GTX with the stock cooler (based on the NVIDIA reference design with no factory or user overclock) while playing Supreme Commander at max settings and it peaked at 98 CELSIUS (81 C idle)! That's extremely high when you consider that water boils at 100 C. I believe the threshold of the GPU is 130 C...but still!! With the HR-03 Plus, the card idles at 59 C and peaks at 70 C while running the same conditions in Supreme Commander and making no other changes to my configuration! It continues to amaze me how much money these cards cost, yet, the manufacturers put on the cheapest cooling solution that they can get away with. I recommend a 92MM Zalman (ZM-F2) or Rexus (Panaflo)FBA09A12H fan (both have a bottom lip that is needed for the quirky fan clips)

Pros: Amazing performance out of this heatsink , using HRPM high CFM fans will give you that extra performance if you need to overclock. beatiful finish , really cools down the monster inside my 8800Ultra.

Cons: In order to have the memory heatsinks to attach properly , i recommend cleaning the memory modules one by one with isopropyl alcohol 96% or higher % with Qtips. when dry apply a good ammount of pressure. You need to know the way the thermal pads work. As you use the video card and the memory heats up the thermal pads will melt and stick to the memory modules and heatsinks very well , my walkaround for this problem was to turn my case upside down for a day or two while gaming hard for looong hours in order to have the memory modules hot , whith the heasink on top as well as the memory heatsinks making pressure downwards they attached properly that way and not fear of coming off never again , the memory heatsinks will stick very well that way without becoming loose, once they attached they are very difficult to remove.

Overall Review: My 3DMark06 score its over 16,000 with a single card on air, this heatsink outperforms most h2o set ups when use with a good fan. Go to guru3D.com and see for yourself my breath taking records on air using this heatsink with a Delta fan 120x38 220CFM , My 8800Ultra overclocks to 756/1280 using this heatsink. sincerely: chispy ,team Guru3D.com overclocking team.

Pros: HSI heat sink now fits on a 8800 GTS w/o mods.

Cons: -

Overall Review: Newegg - please update the product specifications which say: "For 8800 GTS card, a seperate HSI heatsink is required". The included HSI sink DOES FIT on a 8800 GTS as it is the new model.

Pros: Definitely gives me some peace of mind knowing that my load temps stay around 65C. Love the look, pure muscle.

Cons: Went the thorough route and cleaned the ram heatsinks and then glued on using the Arctic Silver products. Real tedious, but once again achieved peace of mind knowing they won't fall off.

Overall Review: If you're buying the heatsink and card together, be sure to test out your video card first. I was eager and went straight for putting on the new heatsink w/out ever testing my 8800gtx. Turned out OK, but I should've made sure the card worked first.

Pros: I took a hell of a chance on this thing. I bought the 8800 GTS not knowing that it wouldn't fit in my BTX case. I didn't want to return it for a worse card at more money. The EGVA tech support guy mentioned off-hand I could replace the cooling. He didn't know of one though. This thing takes up a ton of space, but I thought it might just miss the components that block the stock cooler. So, I bought it having no idea whether I would break my card or even get it to fit! But, it fit, and once it was in... NICE. My 8800 GTS doesn't break 66C (using the Ntune tool) no matter what. Not even running Oblivion at the highest presets in the most complicated scenes. And that's without a fan attached! I have one just jury-rigged to point in that direction. And, my case has only has one fan and nothing special to it. Very impressed.

Cons: If you are like me, you've got a project ahead of you. But it comes with everything. HSI heatsink didn't fit without cutting the corner off. I requested the GTS replacement but didn't receive it yet. Memory heatsinks could stick a little better, but I don't think they'll come off.

Overall Review: Thanks to EVGA tech support. I might never have got the card working in my system without replacing virtually everything. But now, I'm running better than stock temps! And it didn't void the warranty.

Pros: Complete VICTORY!! This is the cream of the crop. I did a lot of research before buying another ”wonder product”. With the confidence of other’s reviews I bought the Thermalright HR-03 Plus. This is great! I cannot believe the temp differences from before. For the 8800 there is no better cooling product short of liquid cooling. The one thing I did different from the product’s instructions and everyone else’s recommendations was instead of installing a 92mm fan; I went with 2 ea. 80mm and mounted them side by side. They fit perfect with zip ties!! Also since I have a 680i MoBo and the motherboard fan being in the way I carefully bent the heat tubes out to 90 degrees from the MoBo. Remember the key words carefully bent. The heat tubes will kink if you take it too far but I had no problems.

Cons: The only problem is the thermal tape used to attach the memory heat sinks WILL NOT HOLD! Why Thermalright went to such great lengths to make this near perfect product and to skimp on something this simple? The tape that comes on them WILL NOT HOLD! I went to "the online auction site" since NewEgg does not sell any and bought double sided-thermal tape for a couple bucks and it solved all the problems with the heat fins falling off.

Overall Review: Bottom line -- THIS IS A MUST BUY PRODUCT! Buy the tape separate and just replace the old stuff on the heat sinks right from the start. Then you will have the PERFECT COOLING SYSTEM for your 8800

Pros: See other thoughts for system specs. overclocked to 575/900 at idle = 53 deg. Overclocked and playing supreme commander = 58 deg. Overclocked and playing bioshock ("fontaine" @ 1600 x 1200, max details) = 59 deg. Nvidia's lame "stress testing" = 57 deg. Couldn't get AtiTool to work though... Installation was a piece of cake. 90% of the hour that it took was ensuring the memory chips were as clean as possible before putting on the silly sticky mini heatsinks.

Cons: With stock cooler and stock timings: idle with fan @ 50% = 58 deg. Idle with fan @ 90% = 53 deg. Playing supreme commander (saved game with tons of stuff blowing up all over - dual screens, max detail 1600 x 1200) 78 deg on 50% fan and 59 deg on 90% fan. With HR-03 and 92mm fan using stock timings: idle 51 deg, supreme commander 57 deg. Bleh. I can't mount it with the heatsink on the bottom of the card (towards top of PC when installed) because of the 680i NB heatsink/fan.

Overall Review: I used everyone's favorite silver paste. 8800 GTS with 92mm panaflow in a Thermaltake Armor case with 25cm side fan, two exhaust 120mm fans (one front, one back) two 90mm exhaust fans (one back, one top), one 120mm intake (front), and one pci exhaust fan (mounted one slot below the 8800 GTS with the stock cooler and mounted on the last slot with the HR-03. C2D 3.2ghz (ultra-120 with 2 120mm fans), 2 gig corsair dominator (underclocked with cooler). "Stock" settings were 513mhz core speed and 792mhz memory. "overclock" settings were 575mhz core and 900mhz memory. Ambient case temp was 28.5 during the "stock" testing and 28 deg after the new heatsink (both with stock settings and the overclock). Ambient room temp was 22.5 deg with the stock cooler and 21 deg with the HR-03. I'll mess with it and post another review.

Pros: I just bought this and all I can say is wow. Brought my idle temp from 70C+ to 50C and load temps from 80C+ down to 55C. Almost a 30 degree celcius drop in load temp. A TOTAL must have for anyone who does more visually than text, and if you have this card I would hope you do!

Cons: For over $50 should have come with a fan, they are cheap.

Overall Review: Install can be a bit time consuming if you don't just use the adhesive tape on the sinks, which I like many others would advise against. It's an extra 10 bucks for the Arctic Silver 5 and Arctic Alumina to help ensure this product doesn't fry your $500 card by having a sink fall off
