hello TPU, recently i bought a coolermaster aquagate viva watercooling kit, and tried it on my overclocked 9600GT, to my delight temps are awesome.

now i want to use this kit with my 4870 (and maybe another kit for the second 4870)

so it looks like the mounting holes line up, so the water block will fit, im just unsure exactly what else on the card needs to be kept cool, as i have ahd to cool G92 VRM's before on modded cards.

i KNOW this kit is probably the worst out there, i don't care, im not after suggestions on a better water cooling system so don't even try.

i'd just like some opinions and/or conclusive evidence on what other components/mosfets on the card that will need cooling.

TY in advance TPU :D

The GPU and the video memory both need to be cooled. On some cards there is a volt regulator but I'm unsure if that gets toasty.

If the waterblock covers the ram and core you should be fine.

Benchmark Scores They're pretty good, nothing crazy.
General rule of thumb would be to cool whatever had thermal tape over it on the original blower... :toast:

worst answer ever, I know.

Or compare the size of the waterblock contact to the size of the original heatsink. (Pretty much what Phanbuey said if you think about it...)

I'm assuming you'll be overclocking, at least a little bit. If you're looking for optimal temperatures and stability, here's my recommendations for proper additional cooling for an HD4870 using aftermarket cooling and/or water cooling...




RED - Needs to be heatsinked. Active cooling is necessary.
YELLOW - Needs to be heatsinked. Low airflow or passive cooling is adequate.
GREEN - Heatsinking is optional, but not necessary. Low airflow or passive cooling is more than adequate.

Utilizing copper heatsinks over aluminum is preferred, but incurs a larger cost. Go with what you can afford.
