200-250mm fans?

[thedope]

ive got a really crappy case, but instead of buy a new one, i thought i might just put in a really big fan on the side will this mae my case really cool? im thinkin 200-250mm because my case is a micro tower. its sort of 35 cm tall. i cant find any on google (im from uk.)

It's better to use smaller fans to add direction to the airflow than to use a big fan and put air everywhere and mess up the airflow you have already in the case.

Remember heat rises, use that to your advantage.

It doesn't matter so much as the amount of air your pushing as long as it has good direction, the sooner the air goes where it needs to and gets out the better. Putting alot of air in random directions may end up being counter production, as it may circulate around the case and linger for awhile before getting sucked out.

Take a look at cases that are well known for good air circulation and build off those ideas. Antec 900/1200, CM 690, HAF 932, just a few I can list off memory.

jezz the fan will look bigger than hte case LOL j/k, my case has a 25cm fan on it I think, but I know you can't get any without the armor side panal, but I do know of a 22cm(I think) and it lights up in blue if your bothered about that, thats the biggest I seen, for oyur case I would be thinking 120mm(12cm) to be honest becasue a big fan 25cm on a midi ATX like the onces you find on the armor would look silly and you might disrupted the airflow in the case.

Unless you are having issues with temperature then don't bother.

I would take a few minutes and use canned air to blow all the dust out of your fans to make the best use of what you have...

I cut a hole in my case for a 360mm fan. for intake. Works great, way better than wimpy 120mm fans. Just make sure to have enough exhaust fans or vents.

i mean a big exhaust fan. i thought if i can move as much air as possible, it will help cooling if i want to oc

yes it cna but it could also work agisnt you means your case is only a midi that fan covers most and some of the inlet fans, this might leave a pocket of hot air over the mobo, and it may not like that
