What is the best way to cool a TNT2

[Swat5444]

Hello, I have a V770 TNT2 with 32mb ram and only a heatsink on the chipset. I was wondering what is the best way to cool this? I have read about people popping off the old heatsink, but they never say how they reattach a new one. Do I have to get some type of heat epoxy or something? If so, where would I get it? If there is a better way to cool this card please tell me that also. Thanks!

well you could try to put ice over the tnt2, although watch out for the runout of water.
just my 2 cents

j/k

He has everything you will ever need to cool your system with,and he is a great guy also.

The best Video chipset cooler is found at www.tennmax.com (http://www.tennmax.com) I think its called the lasagne or something. Anyways its on my TNT right now, and coems with adhesive tape, but you will have to pop off the old sink. its 20 bucks...I would try the 486 fan first.

AuraEdge,
I'm lookin' for any clues I can get to getting the existing heatsink off my V770 non-ultra. I have a great replacement sink, if I can get the original one off, what is the best way to attach the new one also?
Thanks for any hints,

The best way I here to take the old heatsink off is by putting the card in the freezer for 15-30 minutes. That makes the glue brittle. Then right out of the freezer put a butter knife inbetween the heatsink and the chip and twist. The heatsink should pop off pretty easy. Clean the glue residue off with acetone or nail polish remover. Buy some thermal tape which is probably sold at radio shack and put that on the chip and apply your new heatsink and fan to that.

I use a 486 CPU fan for my TNT2, and it works awesome! The chip is rarely even warm now, including after prolonged 3d gaming sessions.

Radio Shack has them for like $9.95 US.

I simply used a needle nose pliers to slightly pinch in some of the heat-sync fins so that the screws for the fan would thread and hold.

Only down side is that the fan stuck out from the vid card enough that I lost use of the PCI slot directly adjacent to my AGP slot.

Just pick up a 486 fan screw it right to the existing heatsink and plug it in.
That's all you should need, even when using TNTCLK to o/c it.

Swat5444,
Sounds worth trying, thanks for the suggestion.

To remove the glue, I used Carborator cleaner, then cleaned off that residue with Rubbing alchohol, let it dry for about 30 minutes, then put the new sink on. For the new sink, you should use either Thermal Eproxy, or Thermal tape. I would use Tape if it is a sink made for a video card. If its larger, lets say an old Pentium sink or something, then I would use Eproxy, because the tape wont make it stick upside down.

I just added a large (3½") but thin (½") fan to my TNT2 non-ultra. I just use 2 zip-ties connected together to make 1 long zip-tie and have it encircle the entire card lengthwise holding the fan in place. Works great. I can easily clock my non-ultra to ultra speeds and beyond. I run it on a daily basis at 170/185.

[Chainsaw]

This is all good stuff,
hey OuTpaTienT, how did you get the factory sink off of your card?
TIA,

AuraEdge, I doubt it would hurt the chip itself, but I'd sure want to mask the pcba off good if using solvents, (especially carb cleaner),maybe you were just refering to cleaning just the heatsink with that (I hope).
Thanks,

I didn't. You think I'm nuts? Stick my card in a freezer then take a butter knife to it? hehe. Actually I would, but my good sized fan keeps things pretty cool. Plus if I add any height to my setup I'll loose another PCI slot.

[Chainsaw]

OuTpaTienT,
Your thread has inspired me to think about the fact that I really don't have any tangible reason for replacing the existing heatsink with this other one. I too, would probably loose another PCI slot (in addition to the one right next to my AGP slot). I am not noticing any heat problems with the way it is, even when I o/c the card to 170/190. I'm just having a rough time not fixing it just because it ain't broke. If I decide I need more cooling, maybe I'll try more fan instead of more heatsink.
Thanks,

Ive had major personal experience with this stuff. I had this Socket 7 fan that I was dying to stick on there, but it blocked one PCI slot..no biggy since i only used one.

I used the WARM butterknife, carb + Alchohol method. I didnt know that it was brittle when froze, but thought that the glue would be softer when warmed, and less chance of cracking the core open by mistake. I probably screwed up there but it still works....anyways.

BUT I couldnt find anything to make it stick! I tried tape, then rubber bands/thermal grease. The rubber bands worked pretty well, but about every week I would have to reseat them, since it would slip and detatch. I gave up on it after about 6 months (yeah it took that long..im a persistant fella), and got me a tennmax that STAYS PUT always...havent clocked my TNT any higher than I could with the standard sink tho...oh well http://www.sysopt.com/forum/frown.gif

I saw the carb cleaner thing on some website. I cleaned off the graphics core and the sink with the carb stuff. Maybe I should have sheilded the PCB, but I was lucky enough not to find out if I had to..didnt spill any onto it.

The carb cleaner loosens whatever glues left on there.

A slot cooler is the easist way to cool a hot vid card, plus it doesn't require any modifications to the card. An added benefit is that the card can act as an exhaust fan for your case, thus lowering you total system temp.

As for me, I'm currently using 3 super7 sized fans on my CL TNT-2. I have two attached (by screws) to my factory heatsink, and one placed on the back side of the card directly behind the core. For the back fan, I just used some industrial grade double sided tape. I placed the tape on edges of the backside memory chips, and just popped the fan into place.

I can run my card as high as 160/220 (commonly run at 150/183), but no problems with heat. It always stays cool to the touch. Not too bad for a card designed to do 125/150.

O.K. you can laugh at this one but Martha Stewart is never wrong. I have a Banshee that was turning my old AT case into a greenhouse so I grabbed a spare Jumbo fan off of a an old amd 233 and hot glued a few strips perpendicular to the HS fins. The chip went from too hot to touch to a slightly warm HS. I know it sounds about as mickey mouse as you can get but hey, "It's a good thing"

[OuTpaTienT]

Yeah, but using hot glue on a HS is kinda risky ain't it? I mean if the HS ever did get hot enough then the glue will just melt and the fan w/sticky glue will fall on other components.
