you should use the PCMCIA slot to make a heatsink for the hard drive. that should reduce temps.

Thanks trellabor, lemme know if you need any extra info . And sorry deus, I can give you a prototype and directions, but that's it . However, I had some free time before New Year's Day dinner today, and I think I solved the HDD temp problem . I at first tried making a little fan for the PCMCIA slot using an 80mm vantec stealth fan and a plastic bag that attached to the slot. I modded the fan to run off USB power, but the problem was that 5v was just too low of power and most of the time wouldnt start the fan. Also, the fan would draw a ton of hot air over the harddrive in addition to drawing air away from the video card fan, so all the components got much warmer than without it. After scrapping that, I came up with the idea of isolating the hard drive.

I cut a jewel CD case into slots and slid them in between the PCB of the mobo and the HDD enclosure.

Then I super glued anti static foam at the top so that it would make a tight seal when the palm rest was pressed down on top of it.

Here are three views of the "shield" in place . As you can see, it's a tight fit but it definitely shields the HDD. I ended up adding another piece of foam at the corner and bringing the two plastic slides together so that there would be a tighter seal. Also, I think it creates kind of a tunnel effect over the fins of the RAM sink, so air that's drawn towards the fan in the back should pass over them I would think. Anyway, the HDD stays at least 5C cooler now, I'm very happy with the results .

I'm impressed k6. I'm in grad school and don't dare to fiddle with my 9300 components much. I thought that pin-modding and upgrading to a 7800gtx was gutsy, but you have certainly proven me wrong.

Excellent work, and keep up with your studies young man!

Damn, a jewel case? What will you think of next?

BTW, I like your ruler; you bring that to your classes too?

LMAO!!!

This mod is really great! I just had to mod the heatsink in my desktop but it was nothing like this. I ordered my i9300 tonight and I will order my 7800 as soon as I can, I may try to low the temps too... Hmmm.

Hmmm medical students and pranks

my friend's sister's crowd were known to play darts with the cadavers as a dartboard.....not recommended to donate your body to medical students (i mean science)

*did you no think to switch to engineering/computing; maybe you should go for prosthetics, overclocking knees for fat babyboomers

Pimp, isn't it

Lol, thanks guys. And I would understand being nervous about your lappy, mine is my lifeline at school. That's why I wont volt mod my video card, and that's also why I do my mods over vacation. If everything is good and stable for the 3 weeks that I'm home, I'm happy . Also, I haven't done anything over the top here if you think about it: added a copper plate to the RAM to keep it cooler and added a a plastic shield to the HDD to keep it sectioned off from the video card. The most "dangerous" thing I did was mod my stealth fan to run off a USB port, if I screwed up the wiring I could have blown a USB port, but that's it .

yea umm i ****ed up the copper mod thing. My own damn fault anyways, so I fried the card. Lovely green boxes, and all sorts of white lines and messed up characters and shit. That was a **** up, next time, I will jsut stick with AS5'ing it up.

Oops

Holy shit, does it not work even with the stock plate back on? You might have touched a component . Shit, try going back to stock and seeing what happens. I'm hoping you didnt permanently damage anything, good luck man.

nope, we be fried. Stock everything, same crap. Meh im not worried, I have my old 6800 back in it. I told them it stopped working and they r sending me a new one, so we shall see. I didnt attempt an exact mod u did. I just used some copper plates that I had floating around, and AS5'ed them to the core, and the heatsink to keep them in place. How thick was ur copper plates? When I get the new one, I may attempt another cooling mod to knock her down a few more degrees lol.

The more and more I'm looking at this, the more and more I'm thinking Ceramique might be a better paste for this than AS5. It's thicker and roughly has the same thermal properties.

Also, they DO make PCMCIA slot fans

I never tried ceramique but I research on both AS5 and Ceramique before buying it. The result was due to some test AS5 was a little cooler than Ceramique by 2-3 degree... (i think). AS5 was a pain to remove in the beginning but once u get used to it , you'll be ok. So make sure you do research before buying those thermal compound.

Honestly, all thermal compounds are good within a couple of degrees, it's all about how you apply them . Thanks for the link to the PCMCIA fan, but I think it'll do more harm blowing the hot air back into the case . Also, it seems that they dont work in XP due to power regulation and XP not powering the slot when no data pins are present.
