Airflow

neokenzo

There's about 5 fans on my casing and I think they are all set at max speed and yet its the temps are not that good. Its probably down to airflow in the case. My fan settings:

1 fan on the top of the case. I think its blowing inside.
1 fan in front blowing inside. (mainly for the hdd)
2 fans on the side window also blowing inside (blowing towards the graphics card and other cards)
1 fan at the back blowing outside

Is those settings wrong? Any suggestions on how to improve the circulation of in the case?

heat rises so it stands to reason the top fans should be blowing out to get the heat out of the case !!!!

Yea, I'd set 2 fans blowing in and 3 fans sucking out.... you want to get the heat out of the case.... Physics tells us that Cold air will move to fill warm air.... hence the natural air flow is from cold to hot...

agreed flip the top fan

Does it make any difference that the 2 side fans are not blowing cold air from the outside? They are just blowing in, lol.
I thought of flipping the top fan a while back but there's so many wires i keep at the top, that I thought chances are, hot air cant past it.

You could always try tidy up the instide of your case, or invest a couple of hundred euro in water cooling!

Why have any fans blowing in at all.

If they all blow out, then a partial vacuum will form, and air will come in through the vents that are in the case.

What exactly is so bad about your temps ? Like how high are they ? The FX-55 makes an can make an awful lot of heat when overclocked. I'm assuming you have it overclocked because you'd be mad to buy an FX-55 and not overclock it!
If you post your temps we might have a better idea of how good or bad they are.
Ideally your air flow should follow the ATX spec, that is cool air coming in from the front bottom and blowing out the back and top. If all your fans are blowing in they'll all be pushing against each other and doing very little good at all. My system only has a single exhaust fan and is ice cool

Thats assuming there are any vents not covered by a fan! Tbh any airflow created with partial vacuumn is going to be much less than a good set of fans sucking in cold air at the bottom and blowing out hot air at the top.

Its surprising the difference a good round of cable tidying can make.


Kenzo maybe you should consider getting some 80-120mm fan sleeves and uprgrading some of the fans to 120mm models?

Well temps are about 37-38C idle although I think the mobo's temps are not that accurate. Thats at stock speed. Thing is, everything seems to run warmer on my rig and thats why I'm asking about the airflow. I'm going to take everything apart next weekend and put everything back together neat and tidy hoping that it will improve temps on my system.
SS, apart from the top fan, all of them are 120's I think.

Dunno if you have them or not in case ya dont Rounded HDD cables DIY style
Might be worth mabe 1-2 degrees - also read the packaged thermal paste is ok to use but using Artic thermal paste maybe worth 1-2degree on the CPU.Lower the heat on the heatsink lower the inner case temp.
Check the spec of your fans as well there might be better out there.

EDIT: another few things airflow linkie see the graphs,also do you have hoods and ducts ? might help even more

MSI's cables are the rounded ones so that fine. I used AS5 on the CPU so that should be fine as well. I was thinking of getting new fans. I dont think the one that came with the case are doing the business apart from the back one. Maybe I should change all of them with Vantec Tornado and then it will definitely sound like an airplane

lol, you certainly won't want to do that. I brought myself one of those cfm monsters when I wanted to try a duct mod for my xp3200+ -- I plugged it in twice and suffice to say, never again, not even 7volted! :eek:
Are the intake fans getting cold air from outside the case? Your temps seem very good considering you have an FX-55 putting out a lot of heat. For comparison, I'm idling at 33-35 and load at 49/51 @ 1.55V on my 3500+

Wait a few more months until the cooling specialists bring out coolers for the DualCore P4 - you will be able to heat a small town in Alaska from those babies - so any cooler designed for it will laugh at your lukewarm FX-55

those temps seem ok. id say though cable tidy is a good plan.

Yup planning to take the rig apart and installed everything neat and tidy
