Peltier Cooling...

[nyzrox]

Well Yesterday mi decided it was time to install my peltier, so i got my neoprene, cut it to size etc to out onto the motherboard, well instead of using unibond(silicone) to glue it to the motherboard i used All purpose Glue, glued the neoprene to my motherboard, put some vaceline in the middle of the cpu socket and put a square of neoprene in there, then put the peltier on, put my heatsink back on and left it for 12 hours. put the computer back together in the morning, switched it on and it sticks on the Boot logo(screen after showing graphics adapter) and it wont change!

My question is, has this glue some how broke my motherboard as i cannot enter bios or anything, or has the vaceline heated up had contact with my cpu pins and nackered it, as there is vaceline now in the cpu socket holes, and on the under side of my processor in the little square hole... if you have a Socket 754 processor you will know what i mean.

i had a pretty stable system before this stupid mod, and now its completely useless at the moment, here is my spec if it will help...

AMD Mobile Athlon 64 3000+ 1024kb LV2 Cache.
Asus K8v-x
1024kb Kingston 333mhz
Akasa Evo-33 with dual Amber fan.

and i think i have a 120watt peltier.

Please note, the peltier was never switched on when it was inside my system as i never turned the PSU on that is souly there to power the peltier.


Any help or advice would be much apprciated

Thank You.

Is the polarity on the peltier correct? Make sure of this so you don't burn up the CPU!

Wouldn't you want the peltier switched on before firing up the CPU since it's acting just like a big heat insulator with it turned off? I mean you're not going to get very good heat transfer to your water block or whatever you've got cooling the hot side with the peltier switched off.

Silicone is recommended to create a air/water tight seal to prevent condensation. I'm not sure that all-purpose glue will create the same effect, but I can't imagine it doing any damage to the motherboard. Likewise vaseline in the socket.

At least you're getting a POST, so you know nothing's dead yet. I'm wondering if it's not overheating and locking up. Have you tried clearing the CMOS? Wouldn't be something simple like lack of a CPU fan signal preventing the system from booting?

i toomall the neoprene off now, i dont get a post or anything it crashes i think, i cant see my post as on my asus board it gives me a fucking screen called 'My Logo' and i cant see post as i press tab and nothing happens, i cant enter the bios or anything. its just stuck...

I am using this cooler top cool the hot side down, do you think it will be ok...?

Although i have dual amber fan

Well, you need a really super heatsink & fan to cool a peltier with air. Most people use water cooling with a peltier.

Take the peltier out, put your heatsink back on and try booting up. My guess is the peltier is insulating because you don't have it turned on and the processor is overheating.

i shall try this tomorrow, im trying to accumulate as much information as i can about my problem.

Thank You for your help Funkz, anymore help is appricated

i have found out that it is the vaseline that did all the damage causing my system not to boot, well i have learnt from this...

im just worried about using silicone, how can i get it off if i want it off!

and is there any decent tutorials around that can show me every place to silicone up!

Thanks again

Suprising. Granted the usual substance used is dielectric grease, but I wouldn't think vaseline would be damaging to electrical components. Have you tried cleaning the vaseline out of the socket? Some compressed air might be able to blow most of it out.

Silicone dries to a rubber-like consistancy that is usually very easy to peel off smooth surfaces.

I would just google for the guides, there's a ton out there on how to prepare a motherboard/cpu for peltier or evaperator installs. Places like Vapochill or Prometria probably have install guides on their websites.

It was not the vaseline after all, i think it was the fact the peltier gets to hot and my heatsink just cannot cool it down! so i have removed it from my system, and my look into just a water block from danger dan just for my cpu socket!

anyone else have any better ideas? also what do i need for a water setup?

[nyzrox]

Just to let you know, i have found out my peltier is 172watt

If you use a pelt use what has been proven to work out there. Using silicone is the best way to seal around the CPU socket. Neoprene is a must for both the front and backside of the mobo. Die-electric greases would be good to fill in the CPU socket pin holes and fill the middle of the socket with silicone and put a patch of neoprene piece cut to fit on top of it. This is what I see most people use without any problems. If you need some more help, I could possibly dig up the links on how to install the pelt.
Also watercooling a 172W pelt is much better as a HSF is just a NoNo!!!

Think about it this way, a HSF is only meant to dissapate heat from a stock CPU, even aftermarket ones are a little bit better. So putting on an additional 172W of heat will cause a lot more harm than good. You're at the point where watercooling is no longer an option, it's a must have!
