and a power supply fan (of course)...
also, the system has typical components (no extra hard drives or expansion cards, etc).|||No case cooling fan is not critical for your PC. However, if temperature is high in your region then you need to have one. Also you need to see how much dust is in your area. If your computer gets too much dust then you require case cooling fan. Beacause dust will block holes and if gets sticked too much around CPU then CPU will overheat causing damage to motherboard and processor itself.
Its wise to use fan always. Its very cheap and inexpensive. In India you get good fans for just 1 dollar.
If you use computers for gaming and extensive programs then you definitely need case fan. If temperature or dust is not a issue then you don't need a cpu case fan.
sometimes if you have poor quality cpu which produces lots of heat then you need case fan. Also check what is the temperature of your PC. If its over 36 degree celsius or 100 degree Fahrenheit then you must use case cooling fan.
To check your cpu temperature go to BIOS. To go to BIOS check your manual. Usually its pressing del during bootup process. or sometimes F1|||It depends on a lot of things. Most computers don't need it, even for intense gaming. It becomes important if you over clock your computer or if, for some reason it's not cooling properly. Now, most extreme computer builders don't even use cases.
Case cooling is essentially a mean to circulate air in the case, pulling "cold" air in and pushing hot air out. If you suspect your computer isn't ventilated properly, it can be useful to keep your CPU running at peek efficiency for a long time. But in no way is a case fan "critical" unless your computer hangs and reboots telling you there was a heat issue. Computers CPU can tolerate 70c non-stop without any problems.
It's not critical or needed unless you want to push your computer to the limits. Some people prefer taking out the side panel rather than install fans.|||Yes, you need a case cooling fan, for two reasons. First, the power supply exhaust fan(s) were meant to cool the power supply. As a side-effect, they also have some cooling effect on the rest of the case, usually. But not enough to cool the whole case by itself.
Second, if you have no case fan then the airflow through the case is wrong. Good cases are made to direct airflow through critical areas to eliminate hot spots. The case can't perform well (cooling wise) if no air is moving through it.
Another problem with no case fan is that your PSU fan is not creating negative pressure inside the case. This will draw dust in through your optical drive (not good).
You don't need a lot of case fans. Many people go crazy and install 4 or 6 or 8 case fans. (why, I don't know) But you do need at least ONE case fan. Ideal use of the case fan (if you only have one) is to have a 120mm fan down low in the front of the case, pulling cool air into the case. But an 80mm fan will work here, too.|||Yeah. Think about it.
It would be like having 2 heaters on inside of the house and having 2 fans blowing the air around the living room. You need an intake fan and an exhaust fan if you want any cooling. Sure you can go to Best Buy and purchase a cheap computer with 1 small fan. But.... that computer has low-power components that don't get that hot.
The hefty CPU's that are out these day run on up to 125 watts at full load. I have a core i7 computer. If i'm running a CPU stress-test the case is warm to the touch. In your case, you might be able to let the computer run at idle and surf the web, but a CPU intensive task will probably push you to the Thermal Max (TJMAX)
If you want a cheap 120mm fan, you have to buy a Yate Loon. You can find them for $3.99 on the internet.
The CPU fan doesn't blow the air out of the case.
Only the turbine and shroud cooling devices on a graphics card blow air out of the case.
here you can see that some power supplies aren't desinged to exhaust air from out of the case.|||Critical no. Should you get one if you can afford a $7 fan, yes. Airflow is pretty important for your PC. If you simply have a bunch of coolants in the PC but nothing to move the air around really, then its kinda counter active.
Like i said, you can find a case fan for $5-15. Pretty cheap and super easy to install.|||Power supply fan YES.
Cooling cases are mostly for show.
If you have a Heatsink with a fan on the CPU, a power supply fan and an external case exhaust fan, That is just fine. No need for the cooling case(usually just means more fans).
