Help airflow problem

post #1 of 4
Thread Starter 
Hello i have a Coolermaster sniper BE case i bought a shark 140 mm fan and a thermaltake 120 mm both 95+ cfm now the 140mm is on the bottom as intake along with front and side the top and back are exaust. now my question is before i replaced the 120 mm fan the temps were 8 c less at full load then they are with the 96 cfm 120 exausting it moves a looot of air. question is do i have to much exaust and not enough intake... should i turn the top one to inake would that fix the problem or should i put the stock fan back in and put the 120 on the side replacing the 200 mm on the side panal as intake ???? and i got a tuniq tower extreme 120 with the stock 2000 rpm 90 cfm fan i think that the therm 120 is 2500 rpm could that be causing the promblems ????

It would be a lot better if you had pictures.. all these intake exhausts are making a mess in my brain . But generally you want fans on the lower areas of your case to be intake, and fans on the higher areas to be exhaust. Usually the top fan is always exhaust, the back fan is always exhaust and your front fans would do intake and your side fan would do intake. This setup works well for me.

edit: ps are you talking about temps in your case or your cpu temps? If you have a push pull configuration on your CPU and the fans don't match CFMs they can cause conflicts.

yes cpu temps case temp never goes above 30 c around 27-30 the cpu temps i ment and like i said the tuniq has a fan 90 cfm on the inside of the cooler facing the 2500 rpm exast fan and like you said i think its causin problems wires have been redone so it looks nicer but thats the set up 3 200 mm fans as intake i put a 140 mm on bottom as intake and replaced the stock exaust fan which i think is causing a push pull problem with the cpu cooler so im askin would i be better of puttin the stock back on and moving the 200 mm and puttin the 120 on the side ??

Remove the rear exhaust fan. Cut out your rear grill. If you have a big open space your air finds its own way out.
