my pc still dont hhave a casing lor...
will update my naked and very messy cable pic later

I would say wrong ventilation air movement.

Air should move from bottom right (below HDD) to upper left (PSU)

Also, the air should go out at the back panel (left middle), but instead, air is going opposite direction (fan above GC)

You should do some study on HVAC

yeah..better u stick one more fan to the rear panel of your case..i cant see any fan there...better stick it for better air movement...suck that hot air out..! cheers...

the design of Dell PC since year 2006 is this type if I remember correctly...the air will be in from rear casing and exhaust thru the front of casing where the air flow will go thru the heatsink of proc...and it is meant for quite cooling solution, and it is btx style...to improve the cooling for this casing, you can put a casing fan to intake from the rear like what you have done (not sure you make it exhaust or intake at rear), remember to tie it if there is no screw hole...dun hang it there...

as for the fan u put besides the hdd there, I not sure there is any intake for the air to get in...if possible, try to make the fan to blow thru the hdd will be better for cooling the hdd...or make it above the hdd...you can try your own way and experiment with it, rather than asking us here coz we will not able to predict the result by seeing the photo alone...hope this help...

the fan u have sitting on top of ur GC is facing the wrong way ler...right now its blowing the hot air from the vents back into the GC fan....turn it around so that it exhausts the hot air out...

inside he made turbulence already....

haha ya.. and why there is a fan below the GC?? and you didnt screw it instead just place it there..

Cannot screw so just put underneath..

haha yaahh i know bout that.. when i take photo that time i didnt notice. hehe.. thanks =D

Anyone sees any largest fan?

go and see at electronic hardware supplier shop.. i think u can find many type of fans there as told by my friend..hehehe...

it will spoil ur GC..better change a casing that can put fan at the side panel..

Threads merged.

i m using casing cm690 , anyone know low yat where can buy a fan 80x80x15mm for right side panel ?

i believe u need a low profile fan for that. try ask ngbh, i think he got some fans like that...
