All I can say is WOW!

I installed a Thermalright HR-03 PLUS on my 8800GTX last night, and I'm pretty amazed with the results.

I thought that it was going to be a difficult install, but it was surprisingly easy. I was a bit shocked when I removed the stock cooler to find that only about 40% of the GPU was in contact with the heatsink! After I got all of the goop cleaned off with TIM cleaner, it was pretty straightforward to attach the heatsinks to the RAM etc, and then attach the main cooler to the GPU.

I expected it to block all of my PCI slots, but the bottom one is well clear, and this is with a Zalman 92mm fan attached.

My temps with the stock cooler (fan on auto) were: -

Idle - 57c
Load - 77c

and with the HR03-PLUS

Idle - 41/42c
Load 51/52c

That's 15/16c off idle and an amazing 25/26c off load

Oh, and I managed to OC the core to 648mhz compared to the 621mhz maximum with the stock cooler! It may even go higher, but I didn't have a lot of time last night. So the reduced temps were with the core running higher as well

Of course the other good thing is that the cooler looks really cool, although when I showed the missus, all she could say was "it's just a big ugly hunk of metal" But she is a woman after all.

I would highly recommend this cooler to anyone who hasn't got more than 1 PCI card. For the performance it gives, the price is very reasonable. I've seen people with watercooling not reach these low temps

Excellent results similar to my GTS Its a great cooler I just found it a hassle at times during installation with a few heatsinks not applying well

You'll most probably have to volt mod the card if you want to go higher than 650 MHz

Mine locks up when I go to 650, yet the temp is only 61C

Yeah, that cooler is brilliant. I installed one veersion of it onto my x1900xtx, and its nice to know how much the temps dropped under load etc...And another plus is its god knows how much quiter than the stock cooler =P

my max core is 660mhz at the moment but whats so bad about that or 650 because thats an increase of 150-60 from stock core is good tbh!

Your core is most likely 648 - the core speed goes up in increments of 27, which is the reference clock. It's the same for the memory.

You should look at the monitoring screen in rivatuner - it shows you the actual core/mem values.
