Better Cooling for the 7800GTX - Page 6

Yah, the cooling is definitely and issue. Here's a little attempt I made at a cooling fan a couple of weeks ago. I never posted it because it wasn't much of a success .


Basically, it was a spare Vantec Stealth 92mm that I had. I cut a gallon sized plastic bag and wrapped it around the fan to make a tunnel. I then made a cut out for the PCI slot and the cut out fit over the slot to suck out air. I then cut apart an old USB adapter and used the pins to have the fan run off USB. The problem with this design was it had several issues. First, while the fan was a low speed fan and drew less than 100mA so that it could run off USB, however it would not always start with only 5V, as very few fans can do this. Also, the air flow was a problem as it drew air away from the system fans and actually made everything hotter . Finally, the design was flimsy and really needed to be soldered to have a secure connection (not electric taped ). Anyway, back to the drawing board .

I'm still suprised noone gone out and made a custom watercooling unit for the 9300.

Thought about it, but the space and power constraints would make it insanely difficult. I dunno, I'll post my blue prints later

Holy crap. There's something really wrong with that, and it's more than the stock thermal pad.

50 is normal stock temp, 70 is high stock temp. which is it?

right now im oat 64 with cpu on low and video on off.

That's your CPU temp? I think fetz was referring to his CPU temp:

That's just ridiculously high for a CPU idle temp.

A follow up to my mod on cooling the 7800 without modding the card. I bought two of these fans and hooked them up to a 12 volt power supply, they work just fine at keeping the 7800 around 77c under full load. My question is this (and i'm hoping K6 would maybe suggest something!):

I have these fans situated at the vents on each side blowing air into the system. I have racked my brain as to how i would connect them to the chassis of the 9300 so the remain more "fixed" and in place. I dont want to make them permanent, just some sort of clip on or support. Any ideas would be helpful!

I'm usually at 41-46c idle and under 70c full load (playing source with everything on high).

It took probably 8 applications of AS5 to get it where I wanted it to be. I think the secret is in the high purity isopropyl alcohol.

Well, here's a turn of events: the 7800GTX is SOLD! . Yah, I have a friend here at college who liked the custom design so much that he gave me a large sum of money for the card. New GTX should be coming in the mail by the end of the week . Although there will be no modding on this one as I am in college now . Anyway, with luck it'll be a better overclocker than my previous card. For now I have this POS X600 which doesn't even recognize my LCD as 1440x900. Oh well, could be worse .

Hmm, celtic, lemme think of something and get back to you. Btw, what power supply are you running them off of, do you have a pic? Maybe you could do something with that?

Btw, another cooling mod by another member of the forum should be up soon, so look for that

lmfao

Condensation would be a problem there, but hey, not bad to start with . Damn I have class tomorrow, I'll see if I can get that water cooling design up by tomorrow. Basically it involved taking out the optical drive and using that space for the pump and resavoir. You would have to remove the USB from the side to make room to push the fan back and then you could put a smallish heater core in where the heatsink which would have a direct route to the waterblock over the CPU. Screw it, lemme get something up here quickly .

Ok, here's the rough design I had from when we were discussing the possbility of doing 2.0->2.66 and 2.1->2.8 Pentium M pin mods:

The copper squares are the radiator and the waterblock (remember that the fan must be moved back), while the blue box is the reservoir and the red box is the pump.

You'd need a low profile pump (I think swiftech makes a 12v model) and a nice flat reservoir, but it's all possible. Tubing would have to be 3/8" copper pipe, but this is all possible I think. I guess you could add a loop going to the graphics card, but I think it would have to on 1/4" pipe to fit. But this would be good as it would increase the speed and should keep the flow rate up enough to be plausible. I dunno, anybody here have alot of expertise in water cooling? I've only built a few WC desktops. Of course power for the pump on batter would be a pain in the ass. Maybe it would be possible to make a hand crank mechanism to get the pump going for 1 minute or so to cool the laptop down while in low power mode. Gaming on battery would be very short though if it had to run the pump .

I remember someone putting a Kingwin waterblock in an ASUS Z71A. The article was on overclockers.com.

I tried finding it, but no dice.

Wait, you've modded your 7800 gtx by using external fans, putting copper in... youve left the cpu? Now youre thinking about ocing it, and since itd get really hot, you wanna add water cooling, and take out the cd rom drive? ohhhhh boy ^^. Can a 770 be pin modded?

Twas just a thought . Honestly, thermal output isn't an issue in these laptops, it's volts. Maybe if the BIOS had ANY overclocking options we could worry about heat output, but no .

And no, the 770 cannot be pin-modded. Only 7x5 series P-M's can be pin-modded as of now.

I really like your high-tech blueprints K6. You're a 1337 MS painter.

You're crazy though, what will you think of next? Water cooling, RAM cooling, extreme pinmodding...some good stuff there.

I think the only person who could ever "extreme" pinmod a 77x/78x would be that guy with access to the 780 engineering sample. It's theoretically possible that that chip could be pinmodded for full multiplier control - it's just I'd only expect 17.5x and 18x to be usable.

"ES" chips are usually initial builds and thus, not always the best for overclocking.

i dont know if Mr. K6 can fit this is but if anyone can, he's our man.. im sure its not that hard to squeeze this little puppy in.
