this new computer overheats badly. my old amd used to get up to 52 degrees while compiling stuff and having a 3d game running. this one goes up to 66. a friend of mine said her brother uses water cooling.
what's that? how hard is it to install and how much does it cost?
66 is far from overheating. What kind of processor do you have?
well,
water cooling is a great idea to go with if you are a really heavy gamer and you would like to overclock your CPU speed
not that hard to install just need some hardware experience
about the price i don't really know how much a water cooling system would cost you in Lebanon but i think the range is 100$ --- 250$

You could try a ThermalTake CPU fan because i don't think you will need a water cooling if your not going with overclocking

Well if you want to consider water cooling, you can go either with a pre built kit or buy the components and build them yourself. The pre built kits are usually crappy and take alot of space in your case. Even Thermaltake water cooling kits are crappy. I recommend Danger Den, but good luck finding it in Lebanon. You can also go with a branded cooler (just throw that stock cooler, it's crappy). For me, I got a branded cooler and customized it. Check out the Scythe Ninja 2 Plus, add to it an additional fan; that's what I have :P (believe me, it cools the shit out of a hot quad core, 50 degrees under heavy load, 39 degrees on normal load)
Water cooling is shit compared to a good quality air cooling. This has been proven over and over again, just read reviews about water cooling vs air cooling. If your processor is overheating then simply get yourself a decent cooler (in the range of 50 - 70 $), and that's all there is to it.
water is 9 times more heat conducting than air ...but it is more expensive and fragile .
Water cooling can allow quieter (potentially fanless) operation, or improved processor speeds (overclocking), or a balance of both. Less commonly, GPUs, Northbridges, hard disk drives, memory, Voltage regulator modules (VRMs), and even power supplies can be water-cooled.

you use vapor-compression refrigeration or thermoelectric coolers in place of more common standard heat exchangers. Water cooling systems in which water is cooled directly by the evaporator coil of a phase change system are able to chill the circulating coolant below the ambient air temperature (impossible with a standard heat exchanger) and, as a result, generally provide superior cooling of the computer's heat-generating components. The downside of phase-change or thermoelectric cooling is that it uses much more electricity, and antifreeze must be added due to the low temperature.(a thermo electric device can be used - AKA 'Peltier junction')
Additionally, insulation, usually in the form of lagging around water pipes and neoprene pads around the components to be cooled, must be used in order to prevent damage caused by condensation of water vapour from the air on chilled surfaces

Thank you for some in depth view but that doesn't change the fact that water cooling for processors is simply not efficient enough when compared to air cooling. I have a lot of resources to back up my claims however the articles range from 2005 till 2011. Here's a very recent review (2011): Destroying Stereotypes: Corsair H70 Liquid Cooling System Review.


From the conclusion of the review:
Corsair H70 failed to destroy the stereotype that compact liquid-cooling systems are not as efficient as super air-coolers. Again a cooling system like that proved to be less efficient than the best CPU air-cooler.
I am sorry Ali but as it is shown in the diagrams the cooling efficiency of the Corsair water cooling system is better.. it is just the acoustic part which can be solved easily .
Also , no direct CPU cooling system was present during the water cooling ..it is wrong
ali.koubeissi wrote66 is far from overheating. What kind of processor do you have?
Intel core 2 duo something @ 2.93GHz

That makes sense. the fan that came with the CPU is running at 1k rpm only :/

Ok, I'll ask the computer store on Monday and see what those solutions cost. Thanks for the suggestions guys :)
ali.koubeissi wroteGet yourself a high end cooler like this baby right here. PcAndParts has this item for 64$ + VAT.
What's the downside of higher fan speed? noise?
What's the downside of higher fan speed? noise?
Mainly noise but there are a lot of technologies put into fans found in high end coolers. For example, the fan found in cooler I linked to has something called ball barrings which reduces friction, noise ... etc ... Even though the noise level increases as the fan speeds up, the noise might simply be non-issue as the noise is very low to begin with.
Intel fans (the ones that come with the CPU) used to be good and silent. AFAIK, it's hard to find a better aftermarket CPU fan, unless you don't mind having the sound of a vacuum cleaner coming from your PC 24/7, or go researching and paying lots.
I have fitted the front of my case with a 12" thermaltake fan which occupies 3 full-size slots (but hard drives can be fitted behind it.
The bigger the fan, usually the more silent. And also more fans is better as long as they are good quality and you can regulate them to have them running at minimum speed. Air tunnels which feed air directly to the CPU can sometimes help too if they're well placed.
If your case is well cooled but the temps on a component are exceptionally hight, it might be the fitting between that component and the radiator. You might have to remove the radiator, apply thermal grease and put it back on and make sure it fits well.
Water cooling is exactly what your car engine has, water is run through it and there is a radiator in front that dissipates heat. Water cooling is efficient and very silent, but expensive and a bit more complicated to install, but above all a bit risky (because of the water in it) and might need maintenance and fixing from time to time. That is why computers are fitted with air cooling by default.
Oh and start by doing some tests with this software:
speedfan
It normally allows you to change the speed of fans in your system, and shows various temperatures. You can see if it helps and get an idea where the problem is.

that looks like a windows application. at the moment, I use lm_senors under linux to monitor fan speed and temperatures
It is. Sorry, I assumed you were using Windows.
rolf wroteIt is. Sorry, I assumed you were using Windows.
Ah ok :) Both applications make use of i2c to communicate with sensors to read temperatures, voltages and fan speeds.

Spot on; as an engineer I get to see both forms of cooling: fans for motors and water cooling systems for IPL crystals. The usage of fans is less risky (no water involved = no chance for leaks and fear of damaging electric systems) and doesn't require a lot of maintenance (unlike water cooling systems where you have to open the tubes every 3 months due to the calcification that will occur thanks to our lovely water supplied by the government, and the water must be changed every 6 months... even filtered water: we use distilled water and have to change it twice a year). However, they are noisy, but some systems surround the motor and fan with anti-static foam:



which by the way doesn't heat up easily.

The simple advantage of water cooling systems is that they can reach a cooling temperature of 0 degree Celsius (yep, zilch) and the object being cooled becomes ice-cold. I don't know much about existing water cooling systems for computers, but I'm very skeptical that they can reach very low temperatures => useless to buy and install.

Go for the fans, and use a sliencer foam.

@Tarek: Peltier junctions cool on one side and heat on the other (Seeback effect). Not recommended.
Best solutions :



Hahahaha, J4D nice one (I especially liked the third solution) xD
