Peltier coolers? Can i make my computer quieter for cheap?

thebluebumblebee said:
OP, your case has an air flow problem and you're dumping a lot of heat into it. You only have a 120 mm fan for an exhaust. IMHO, get a better case with better airflow - and the fans won't have to spin as fast, thereby lowering the noise.

Yes that is my problem. I got a super cheap and shitty case. But i cant afford another case. I was only interested cause peltiers are so cheap to buy. Might look to see if i can get a 5 quid fan controller and just leave the side panel off

Thanks everyone for your advice. Ill probably do a crazy peltier cooling system on an old 771 socket celeron one day but i see that it is not the solution to my current problem but for getting high overclocks

Weird choice as i can only find reference to a
Intel Celeron 445 specifications
http://www.cpu-world.com/CPUs/Celeron/Intel-Celeron 445 - HH80556KH036512.html
http://ark.intel.com/products/35277
  • Status Announced
Did they ever sell them ??????

edit
Celeron 445 is the only known Celeron-branded microprocessor with Conroe-CL core. As the core name suggests, it's a variation of Conroe core, and it borrows all major features from that core: Wide Dynamic Execution with ability to execute up to 4 instructions per cycle, 64 KB level 1 cache, 512 KB level 2 cache, 64-bit instruction set, and SSE/2/3 extensions with Advanced Digital Media Boost, that improves performance of 128-bit SIMD instructions. The Celeron 445 processor has only one core, and runs at 1.86 GHz. The CPU has faster FSB than Controe-L processors - 1066 MHz as opposed to 800 MHz for Celeron 400 series. The 445 model also includes Virtualization and SpeedStep technologies, which are not present on Celeron 400-series CPUs. Despite of it's brand, the Celeron 445 was designed for servers, albeit cheap ones, and therefore it is packaged in 771-land LGA package, that fits socket 771 motherboards.

It does it's job very well though I see, the only problem is that you'll get ice forming....

 
@dorsetknob maybe socket 775 i get mixed up some times. But an old celeron D 352 holds intels cpu frequency world record and they cost about 2 quid each

got 2 Celeron D 352 ( SL96P & SL9KM ) @3.2GHz in my 775 CPU collection also got the faster Celeron D 360 ( SL9KK ) @3.46Ghz

Nice for on a chain around your neck..... :D
 
Peltier is super effective when you efficiently cool the hot side. The colder hot side is (as weird as this sounds), the colder cold one will be. Slam water cooling on it and you'll get insane low temperatures.

Like my Celeron

Well, let me add my 5 cents to discussion.
I've seen lots of posts about condensation and few minor aspects of TEC cooling, but you guys have forgotten one thing: Peltier won't work for OP just from the description of her goal!
TEC cooling plates are not 100% efficient. To be more specific - it's the least efficient way of cooling electronics, if you don't count hiring a High School trumpet band member on a springbreak to blow really hard on your CPU heatsink to provide additional airflow :fear:

Basically, in order to use TEC plates, you have to cool them too. And the heat output will be much higher than the CPU itself. So, the air cooling has to be louder, or water cooling has to be bigger and louder.
The only practical applications of thermoelectric cooling, is keeping something at sub-ambient temps, or giving a cooling boost no matter the noise and cost of electricity.
Might as well submerge your PC into a mineral oil bath to prevent condensation, and stick it into a mini-fridge (it may be even quieter this way).

I have a 125W peltier laying around from a project I tested years ago. I put one on a Phenom II 940 using the stock cooler and two copper sandwich plates. It actually worked great but needed to coat the area around the CPU with either liquid electrical tape or some type of silicon. core temp got so cold it stopped reading even when it was OCed to over 4Ghz. You will need a GOOD power supply to power the peltier along with all of the other components.

I think I have seen some tower like coolers with PCIe power plugs somewhere although I can't find them anymore. Were they functioning in a similar kind of way ?

Even then, because you move to nitrogen or a really awesome freezer :)
There was a few peltier 'ready' coolers available for some time with plates pre-installed, I don't think I've seen one since 2005'ish.

This one you are talking about, this is quite recent.

right guys, my computer is loud as hell and i wanna quiet it down but im broke as hell.

Peltier coolers.

yeah I know, sub ambient cooling means ill have condensation problems but im pretty sure I can eliminate that with enough care and time.
but what im thinking and id like some confirmations on what i think i know and some other things too.
what I know so far is that peltier coolers have a hot side and a cold side. the hot side can get hotter than what you would like a cpu to be at as the cold side is cooling the cpu

so.

at the moment i have 4 noisy old fans in my computer and what i want to do is use a peltier cooler to keep the cpu cool and use my air cooler passively to keep the peltier cooler cool.
i imagine that the hot side will get hotter than you would expect a cpu to get but that shouldnt matter as the cold side will stay cold as long as i keep the hot side's temperatures under control
like this i can get rid of 2 or 3 fans from my system and bring down noise a lot

or should i just not go down this rabbit hole until i have a system that i dont mind killing?

Having a quiet system really isn't rocket science these days, but it does hinge heavily on the choice of components and case. If you make the right choices at purchase, you can have a super silent, air cooled, high performance rig.

- SSD instead of HDD
- Low RPM optimized case fans (and more importantly: all of them the same ones!)
- Fan curve on GPU leaning towards lower RPM instead of combating the last few degrees C
- 100-150w headroom on PSU + a PSU with a good, silent fan
- Low RPM optimized CPU fan
- Case choice: weighty, preferably sound insulated (ie Define R4/5, Silencio, etc.)

The only annoying bit here is that once you start focusing on noise, you'll start hearing everything too :P So either go big or go home.

Peltier? Not on my watch. Keep it simple :) We are well into the realm of having access to cost effective, air cooled silent systems.

Oh yeah i know how to make a totally silent computer but the problem is i have literally no money to spend on components, not even quiet fans.

Sorry about the double post. Im on my phone and im rubbish at using it.

@lyra

If you want fans pop round

I giggled a bit when I read the thread title, I'm sure it's already explained here that a peltier element is extremely inefficient and will output a load of extra heat on the hot side for a small decrease in temperature on the cold side...

You can't really run a peltier element significantly hotter than a CPU either, so it's not like you are going to be mega boosting the performance of any heatsink... Besides heatpipes don't work very well either outside of their normal temperature or power range.

If you want the cheapest way to quiet down your PC, run your fans slower and take the side panel off!
 
I always wondered what happened to peltier coolers. They cooled well but they were extreme... they cost a lot of power to run and they had to be cooled properly (usually in a water loop), and if something went wrong, it went really wrong... and you had to cold prep the computer and all that... but they cooled well! A few members had one but they kinda just faded away...

I dunno if he's still around, but I believe there was a member "Wile E" that had a bad experience with TEC cooling. I mean real bad. I'm sure everyone who's been around long enough remembers that story.

I don't recall many people here or on OCN ever really using them much, but hey, you've been around here almost a decade longer than me. :) I suppose aside from condensation there is the risk that the element blows and ends up heating your CPU up as well as the hot side...

Maybe a safe way to run them would be to use a water loop and have a second waterblock+heatsink where the TEC elements cool the water before it gets to the CPU. That way you can avoid both as you can keep the water temps above dewpoint very easily, you don't really care about condensation around the element itself, and you don't risk putting all the heat that should be going out the hot side straight into your CPU when the thing goes bad... Only downside would be that you need more rad/heatsink space
