Hi all,

I've purchased a Zalman NB32J, originally intending to use it on the northbridge in replacement of a noisy Thermaltake Crystal Orb. Problem is, I can't remove the Orb without removing the motherboard, and I've never done anything inside my PC that is quite that involved.

Plan B is to hook up a Zalman Fanmate to the Orb to quiet it down, but that leaves me with an NB32J sitting and looking pretty on my desk.

I don't have a super-current system (Athlon 1200, Geforce2GTS video), so I'm wondering if the NB32J would be adequate to cool the Geforce2 GTS chip.

I know people have successfully used the NB32J on Radeon 8500 cards - has anybody tried using it on a Geforce2GTS?

I suppose I might give it a shot with the case open and low-demand video. I have an ASUS card, so I can monitor the temps using software. I just don't want to cook the chip.

Any thoughts are appreciated.

Hi Rook,

I have done this mod on both a radeon 9100 (8500) and a GF4ti4200. Both work without any problems. I don't see a GF2 drawing significantly more power that the GF4 so it should work ok. Just make sure that the HS bottom surface is not too small in comparison to the GPU chip size.

Hi,

Thanks for your reply and help.

What kind of case temps should I have in order to ensure that I don't cook things? My mobo reports around 39C at idle. I'm running a Sonata with the stock PSU and 120mm fan.

You will not be able to get away with running it fanless without underclocking the chip. I have an undervolted 80mm fan blowing across the unit.

of course on your own risk as usual, but i can share u my experience with geforce cards.
i replaced the noisy 40mm fan on my creative geforce 3 with that gold nb32j hs without any fan blowin onto it. of course it gets hot. i could even overclock it a bit, but that felt not necessary in my case. by the time i've added the zalman fb123 arm and 92mm. but really all u need is like a papst 80mm at 5v or something to cool it a bit. in my case i dont have to, but thats up to u to discover.

I think you can underclock the gf2 gts core 20-30 mhz without much performance loss (1-2 fps). The limiting factor on the gts was the memory bandwith.

lookee here

do you mean that gf2 gts is more heat producing than my gf3? I said above that i successfully just have a nb32j hs onto the gf3 chip and blowing onto it is not necessary unless overclocked...

What kind of temps are you getting from the GPU (assuming you have a way of measuring them)?
