Can you put the fan under the fins on the SI120?

fps justin · June 16th, 2006

I was just wondering if you could put the fan under fins on an SI120 cuz the dang thing is 9 cm tall. Which means i would have to take out my vent and find a new way to cool my ram. I kind of want it under the fins so i get more space to put a fan ontop of the ram.

Also, this brings me to another question, could i put two fans on the SI120? one on each side? :P

You can. I've seen it done before.

Are you thinking of blowing on the base or on the fins?

It will be a push and pull sandwich configuration. Two exact fans, one on top and one on the bottom. The top will blow down on the fins, the bottom one will suck the air through and blow it on the base.

I don't see there to be too much purpose... If the fans are low rpm/cfm you'll see slightly better temperatures. On higher performance fans, the difference will be minute.

I doubt having two fans on there will really increase performance much (if at all). Although experimenting with different fan configurations like you were saying is not a bad idea. I'm not sure if it will fit actually, you might need to find a 15mm thick fan to get it underneath the fins.

Ditto to that. The problem does not lie really within heat dissipation but with heat absorbtion. The fins are already being properly cooled I think.

ionno, i just need a better cooling solution, cuz during this hot weather, my computer can't run at 2700mhz anymore. =P

I get what you mean. I used to get 38 celcius peek under full load when my case wasn't really ventilated and now I got better fan blowing (and more noise) and my temps are 42 celcius under load. =/ I hate summer.

i'm starting to doubt it is my cpu. It never really went above 38c on load... I underclocked it a bit, back down to 2250mhz with much less voltage adn it still wouldn't load windows properly. I have a feeling it is my ram, cuz my hipset voltage was also only 1.6v. Only my ram was still stuck on 3.2, however, i had a fan blowing down on it, so i'm actaully quite puzzled right now.

yeah i'm prolly right, i put all my fans on full blast, which is freaking hella loud but it works... i need new ram for the low noise level i need.
