should the CPU fan blow the air towards or away from the CPU?

That might blow dust into your CPU.\n\nI do not think the performance of your computer is because of the fan. It is probably a coincidence.\n\nTry going into your task bar and see what else is running that might be slowing you down.

what are we trying to do? Remove heat from the computer so it does not burn up. One way is to bring cool air and push out warm air. \n\nA fan does that and oh Yeah ....... it really really low cost.\nAnything else will increase the cost and you don't really want to do that do you. The more it costs to build it the more you pay for it.\n\nYes there other methods ... I know all of them but they all cost more money .....

normal. but if your computer is in an encoles space on most sides, it could be overheating. just move it out into a more open area. the noise should die down a bit. but it is normal. the buzzing means that all of the grears are moving properly.

I think there is some problem with your fan. I am using computer in bangladesh without AC and sometime in summer I run my computer for 3 to 4 hours without any problem. Consult with your vendor and if you are covered with warranty claim co change your CPU fan.

More likely, your fan is bad.  If it was the power supply, you would notice more issues with the actual computer.

Put something under each corner so the computer is an inch or two above the table. Place a fan so it blows air under your laptop. This is basically what a laptop cooling pad does. It is a box with a fan that cools the bottom of the laptop.

Think Ive got this, Use a static Cuff, Remove heat sink and clean the fan (tooth brush is good for Heat Sink Fins and cotton buds for the fan, remove Thermal paste (carefully) white spirit or lighter fuel liquid, apply new Thermal paste to the top of the CPU (a drop say 10-12mm across as it will spread when Heat Sink is replaced, and a drop half that size on the bottom of the Heat Sink rebuild the assembly (fan, heat sink) and all will be Cool.

A blocked or filthy fan reduces airflow across the board and processor. This can cause anything from minor system mis-behaviors, to complete crashes, to running for a time and then powering off. This also causes damage to the board, processor and hard drive.

Check your Cmos setup, if there is no setting for the fan, then i would not worry about it, it better to be cool than hot....It must be a Dell, just joking.....they have the most complaints....

50C is 112F. That's pretty warm for the interior of the box but not really too hot for the CPU itself. Install another fan at every possible location on the box. Two on the back is good plus one in the power supply. Make sure the air has some place to go, don't block the vent. Also make sure there are places on the front for air to get in. You want air going from front to back, quickly and a lot of it. Reposition the cables inside the unit to prevent air blockage.

If you mean the wind is blowing spray toward & into your house, more fans alone won't help; you should add filtering if possible.  Since most computer fans exhaust, and the intakes are all over the case, maybe it would be easier to put the computer in a small room with a recirculating air purifier (fan & HEPA filter).  This would help preserve the peripherals too.

The CPU heatsink is used to cool the processor,it takes the air to cool down processor.

Likely you have a heat problem.\nor it could be a fan rotation warning, some motherboards can alarm you if fan speed drops below a set level....\n\nPay attention to it regardless, and have someone look at it !

check if your CPU temprature is high.\nthe most common resualt of "CPU fan" problem is hanging or freezing.\ncheck if your CPU fan is working properly.\nthe next problem may be RAM.try to change RAM and test your system.

Ideally there are 3 fans in the computer: The SMPS (power supply) fan, the Chassis fan, the Processor fan.\nSome computers with some external AGP graphic cards have an additional fan on the card.\n\nAll the fans in the computer have to run (That is as silently as possible) in order to save the system from over-heating.\nThe SMPS fan has to run so that the power supply remains cool.\nThe Chassis fan has to run to keep the motherboard and other components cool.\nThe Processor fan has to run to keep the processor, which is very expensive, from melting.\n\nIf any of these is making a noise (if thats what you mean by run a lot) then check if there is something bocking its way. Or else, its time to change it.\n\nIf its a branded OEM computer (Dell, HP, Gateway, etc) get them to do it under warranty.\nFor all other systems, get a local tech to the job.\nYou can also do it yourself, if you can do a good job with a screw driver and a set of cables.\n\nHope thats what you were looking for.

The right way of cooling a pc is by putting one at the front and one at the back. The front sucking cool air from outside and the back blowing out the hot air from inside. If one of them is working the wrong way, air inside is trap and there's not cooling action.

put a fan in...the temp rises when the air doesn't circulate properly.
