CPU cooling with Peltier (TEC)?

[gustafangus]

Ok, so i am used to playing games all summer quite some hours . Anyway my cpu gets way too hot. (played Crysis on intels i7 920 NOT overclocked for 6 hours and the temps were around 120C!! ). Although i have 8 fans (2X 200mm, 1x 140mm 3x 120mm + 2x gpu + CPU), the dont help because my room is very hot as well, so blowing hot air in to the PC makes no logical sense to me. My friends keep telling me to get water cooling, but im not spending 100$ for something cooling and that can potentialy destroy your pc. so, i found something cool... a peltier! If anyone doesnt know what a peltier is, its a chip, that, when connected to electricity, gets very very hot on one side but also very very cold on the other. If you dont believe me then check this guy on YT who cooled his CPU to -20C!!!

The good thing is that they have a price range of 5-60$, and you know im getting the cheapest one Im getting a new motherboard and cpu now so thats why im asking.

New CPU: Intel i7 3820 http://www.amazon.de/Intel-BX80619I73820-Bridge-i7-3820-Prozessor/dp/B006WVVA28/ref=sr_1_1?s=computers&ie=UTF8&qid=1358707853&sr=1-1

So a couple of things before we continue: Im going to connect the TEC to USB (5V) NOT 12V, i dont want to coldsnap my cpu AND i dont want to go to minus degrees ( like our friend in the video ), because of condesation under the peltier, and i dont want dripping water on my GPU.

I just wanna cool it enough, since im probably gonna overclock the new CPU to 4.0 (0.4ghz up), since its already at 3.6

So my plan is: Put a copper rectangle (so it will be a little wider than the CPU fan and heatsing) on my CPU w/ thermal paste once its instaled on the MOBO, then putting the fan/heatsink on the BACK side of the copper rectangle. Then i wound connect copper pipes from the copper rectangle OVER the cpu fan and make another copper rectangle/square over the fan, and glueing the Peltier there, so it wont be in direct touch with the CPU (for safety reasons).

QUESTION TIME!

1. Can there be power failure due to the peltier being powere by the USB?
2. Can it damage my CPU/MOBO? can i glue a piece of copper on the CPU?
3. Your thoughts?
4. which peltier should i get? Keep in mind that USB has a 5V output. My choices:

Remember, Im cooling, not freezin

I just hope there will be enough space on the mobo...

Sorry for spelling mistakes and stuff, im on a MAC, because my PC is being repaired.

Is there any other LGA 2011 CPU / Mobo better THAN what im buying? (for the simmilar price of course) PC specs (now):

CPU: Intel i7 920
Motherboard: Gygabyte i dont know what
GPU: Asus Radeon HD 7850 2GB
RAM: 12Gb 1600MHZ ram
Cooler master HAF 922
600GB disk

Oh yeah, will a 850WATT power supply be enough for the new CPU and MOBO?

Ask for more info! and thanks in advance

peltier cooling your cpu although it sounds a good idea is impractical

because of condensation--the amount of watts you would need on the peltier--and getting rid of the huge

amount of heat from the hot side

if it was practical then there would be loads of peltier coolers about

think i have only seen one--and it switches the peltier on and off to stop it getting too cold one one side

and too hot on the other

and still needs a great big heatsink and fan

and the actual temperature results arent as good as a good normal air cooler or water cooler

 

[gustafangus]

I would keep it under minus therefore skipping the condensation part , but how about this?

putting the peltier between the small square under the heatsing, and the heat would be destroyed! by the upper fan/heatsink...

 

[mcnumpty23]

still dont think its a good idea

its in the same league as liquid nitrogen or liquid helium cooling-- its possible to do it but not practical

how many watts peltier were you thinking of?

 

[gustafangus]

i dont know... how much wattage can a USB provide anyway?

 

[gustafangus]

Oh, BTW mcnumty23, is the fan i last linked, the Scythe Grand Kama for LGA 2011? somwhere it says it is, somwhere not... Confusing... And if not, can you post any cooler similar (with spacing between the square and the heatsinks) under 50 euro? Thanks

 

[mcnumpty23]

according to scythe website it does fit socket 2011

[gustafangus]

Thanks man.

Just out of curiosity, would the peltier work by USB?

Thanks

 

[mcnumpty23]

i would say no

usb ports only supply about 3 watts as far as i know

 

[mcnumpty23]

heres the only retail peltier cooler i have seen

and that uses up to 70w and 12v

though it looks like they attach the peltier to the heat pipes rather than directly above the cpu

still needs a huge heatsink and 2 120mm fans and the peltier isnt in constant use

[gustafangus]

Meh... too much money, might as well go with water cooling....

 

[mcnumpty23]

how hot does it get in your room?

my second pc has an i7-920 at 4ghz with a corsair h50 cooler with 2 x 120mm fans on the radiator

with no problems with temperature

I am thinking of making a peltier cooler on a Pentium g (Intel Pentium G2120 3.1GHz 3M LGA1155) processor when i build my new PC. I saw Peltier modules on the Jaycar website (http://www.jaycar.com.au/productView.asp?ID=ZP9104). I am planning on overclocking my Pentium to save money on buying an i5/i7. if i combine one of these with a decent heat sync/fan combo would it work? i am not worried about power consumption as i don't sit at my computer for hours at a time.

^ Great resource for how to use Peltiers to cool components.

Though if your going at it to save cost, your in for a hell of a shock.

year, I am probably better off saving up for a better possessor. say an Intel Core i5 3330. I have read that Intel on board graphics have improved a lot. Should I skip graphics card to spend more on processor? i don't want to go spending a massive amount strait up, i would rather buy a basic system and improve it as needed.

 

[manofchalk]

Intels integrated graphics have improved with Ivy Bridge, but their still pretty inadequate if you want to play anything above low settings. If you after integrated graphics, look into the A10 APU or wait untill Haswell drops, which will have a far better integrated graphics than current Ivy chips.

However, a low end graphics card will easily blow those out of the water. Something like a HD7770 will let you play most intensive games medium settings at a decent FPS.

 

[lord slender]

Thanks for the advise. I was looking at Gigabyte GeForce GT210. or Asus AMD Radeon HD5450. Witch would you recommend?. The amd is a silent card, and I have had some issues with these in the past. I would be using Tribes Ascend as a benchmark, as this is the game i play most.

 

[manofchalk]

TBH, at that level just don't bother buying a card and use whatever integrated comes with your CPU. Those cards I would only use for extra display outputs, they are nowhere near adequate for even low end gaming.
I consider a 7770 as minimum if you want to game at a decent level.

Anyway, I think this thread has been fairly de-railed. It seems your after general system advice, so I recommend you fill out this form.

and creating a thread on the Systems forum, you'l get more advice there than you will from an old thread that has Peltier cooling in its title.

From Peltiers to New systems...

Well, this escalated quickly.

 

[manofchalk]

Ahh, sorry about that. I assumed the thread was dead since the post before slender's was from January.
I would say it de-escalated, Peltiers are pretty complex and a system build is not.

No need to be sorry, i liked this discussion, I learned allot.

 

[lord slender]

Thanks for the link. I don't think i will go deciding on any definite hardware just yet, as it wont be until christmas that i will be buying the system. In the world of hardware, a lot can change in that time. As far as peltier cooling goes, i have an old xp desktop that I am going to experiment with it on (i got it for $10 from a dump).
