hello the question is. i have a system fan on the back of my tower case and i have it pointed to suck the hot air out of my case, but the thing is.. its usually sucking cold air out, sometimes hot air but like kinda worm air.. pics are below to show about where the fan is..





and this is to show what my cpu temps are.



is there a way to make my cpu fan and system fan to run higher rpm to cool more?

thanks for the help.

Draw cold air in from the bottom of the case (IN) and suck hot air out of the top of the case. Your big fan could be interupting the airflow to your cpu heatsink, causing elevated temperatures inside the case. Air flow is crucial !

You could also use a duct from the big fan to direct air towards your heatsink fan, that could help you.

Have a look at this builder guide for more info:

Hot air tends to go up, if you put the exaust fan close to case bottom, it doesn't help as it can. Is there any change for you to put the fan upper in the case more close to H&F or in top of the case? Now, if you lock at System temp, it's at 29ºC, well i think that's why you feel warm air exausting; 29ºC is a warm temp...

29 degrees isnt bad at all... I lean case temps are normally 5-10 degrees higher than house temps. So unless your house is colder than 20 degrees its quite a good temperature.

my house is real warm today its hot where i am, the system temp is usually lower 20s on a normal 70'F day but my system runs between 5-35'c, but is my cpu temp hot? im thinkin on getting a pci fan for the bottom to suck cold air in, and use the big fan to suck it out. but if the big fan is sucking cool air then whats that?

also, as i said before.. is there a way i can gain rpm on the cpu and system fan? when i start up its goin like crazy like what it said on the bios, but after it goes down to about 2k to 2.5k rpm and the system fan is like 1k.. to low i think..

An intake fan isn't nearly are important as an exhuast fan, I'd just set it to pull hot air out of the case, maybe put a side intake fan on the case, but again, intake is't really important as long as the case has vents then you are generally covered for intake.

Also, 51C isn't the coolest, but it isn't near the danger zone, so you're ok, what HSF are you using? A good HSF makes all the difference.

If the old one is from a retail 1600+ then no, don't use it. You can get a better HSF which will keep it cooler, but it will void the 3 year warranty, assuming you got a retail pack. If you got an OEM chip, then by all means, upgrade the HSF.

Sounds like you have cool and quiet on that m/b slowing the fans down go into the bios and disable it if thats the case and they will run full speed.
