6600Gt Over heating

Avatar7 · Post by **Avatar7** » 21 Feb 2006, 19:10

Hi all, I have my system running finally after many rectron problems, Yet my grfx card is running 2 hot, its a 6600gt with heat-pipe2, I plonked a large fan loosly on top and now its more stable, but i need a more permanent solution what can i use, any sugestions are welcome!

Any passively cooled gfx card will run hot (well the decently fast ones anyway). Make sure the case has a negative pressure (more fans blowing out than in) and remove the "metal thingie one removes when installing a PCI or GFX card", the one underneath the gfx card. This will force air to run over the gfx card heatsink.

You can also try removing the heatsink, lapping it, and applying some AS5.

If that doesn't yeild satifactory results, then buy a zalman VF700, or wait for zalman's VF900.

Get a Zalman. It's a good investment.

Now there is some good advice. I think I will take that for myself. I have a Colorful 6600 vanilla with stock cooling (a small heatsink and fan), but it idles at about 63*C.

Which is better:

1. Zalman VF700 AlCu Led (Al & Cu)

2. Vantec iceberq5 CCB-A5C (Cu)
http://www.vantecusa.com/p_ccba5c.html
3. Zalman VF700-Cu Led (Cu)
http://www.zalman.co.kr/eng/product/vie ... 3&code=013

They are in order of price.
Is the VF700-Cu worth the extra cash?

The Cu cools about 2'C betterer. The LED verions look prettier. Don't bother with the iceberq.

So this one would be cool?

1. Zalman VF700 AlCu Led (Al & Cu)

It is about R50 less than the Cu one.

LOL. I have an xfx 6600 and it also idles at 63*C (84*C load). As soon as im free im gonna get another one. I crushed the first one i bought before i installed it. Very stupid.

Uh, CiCliC, i think the first thing you should buy is some decent cooling!!! 84* under load is very hot, it's too hot!!! Buy a new cooler before you destroy another card!!!!!

Hex_Rated · Post by **Hex_Rated** » 21 Feb 2006, 23:08

How did you crush your card? 84C is hot, my GTX overclocked loads at 58C, 5C less than your idle temp.

DAE_JA_VOO · Post by **DAE_JA_VOO** » 21 Feb 2006, 23:26

Yeah, but remember hex, that the 7800 series cards are not as hot as the 6800/6600 cards. My 6800GT used to idle at around 65*, whereas my 7800GT cards idle around 50* (right now, the one in my PC is at 44*) on air.

Anyone? AlCu or Cu?

I am leaning towards the AlCu, just don't want to waste any cash.

Hex_Rated · Post by **Hex_Rated** » 22 Feb 2006, 18:34

For R50 extra i'd get the CU. I've got one at home on my FX5900 at the moment, but haven't tested it. Supposed to be a little better then the ALCU.

I crushed my Zalman ( http://www.computersonly.co.za/productd ... ryId=36121 ) not my card. I was sparing with my bro and i stepped on it. I was told 84*C wasnt too bad but now i think im gonna make an effort.

This is the current set up.
this is the heat pipe Which was done by zalman.
and...
this is the extraction around that area, there should be a good air flow in that area, yet overheating is still a problem, any suggestions?

Ok, if you did remove the slot under the graphics card then try block up other place where air enters the case. This will increase the velocity/volume of air moving over the gfx card heatsink.

Make sure that rear fan is sucking air out.

Avatar7 · Post by **Avatar7** » 25 Feb 2006, 23:26

yeah, i got 1 80mm in front sucking in and 2x120mm at the back sucking out.
I sat my old cpu cooler ontop and stability increased, do i think i should invest in a zalman, I want an uber sexy one that will match my red+blue theme!

Bobendren · Post by **Bobendren** » 26 Feb 2006, 00:10

That's looks like a Chenbro Gaming Bomb, correct? Just use some masking tape to plug up all the holes and see if it makes a difference.

Otherwise just slap a fan on the top heatsink, or suspend a fan to blow over the whole thing.

Avatar7 · Post by **Avatar7** » 27 Feb 2006, 16:24

I've tried a few things and stability is still not good, I was thinking of getting the zalman fatal1ty vga cooler, good/bad? And where can i get it, i've tried shops in PMB, nothing. Can i not do a debit order with SA online stores?
Will the cooler fit on the card? this card?

Post by **neon_chameleon** » 27 Feb 2006, 18:07

Yeah it's about the best choice atm. The VF700Cu will cool pretty much the same though. The only difference between it and the fatal1ty version is the red colour and faster fan.

Zalman are releasing the VF900 soon, it's bigger and has intergrated heatpipes. So you may want to wait for that.

I bought the VF700Cu today. I haven't had chance to install it yet though. But I will let you know how well it works. It looks very nice. Blue heatsinks for memory and a blue LED. It is quite heavy though. If you want red LEDs then get the fatal1ty.

Avatar7 · Post by **Avatar7** » 27 Feb 2006, 19:28

I had a look for the vf900 and couldn't find any really good juicy links, Any1 got some?

supagx · Post by **supagx** » 01 Mar 2006, 19:53

I installed my VF700Cu LED on my Colorful Geforce 6600 and I am very impressed. The idle temperature dropped about 13*C and the load temperature dropped about the same. With the stock cooler I managed to get the core speed from 300Mhz to 411Mhz, with the Zalman I can get the core to about 470Mhz!
