Black Ice Extreme cfm requirements?

Shelly · 04-15-2002, 10:05 PM

I just got my water cooling system going (still waiting for someone to tell me how to upload pics) and am using (2) JMC 120mm fans rate at 61 cfm @ only 26dBA each. I have them mounted on each side of the radiator (BIX), with roughly a 1" shroud. My temps on a non-overclocked P3-933 are 35C/45C load. My ambient temp in the room is about 82F now. I am trying to keep the system as quiet as possible (the 2 fans on my ICute power supply are making the most noise, if I could only find out how to disconnect one of them) but I have seen that the Black Ice Extreme is recommended to have at least 100 cfm passing thru it. Common sense will tell me that increasing the cfm with better fans will drop my temps, but at the cost of noise. I have also seen people modding their fans to 7 volts, but basically won't this do the same (cfm and noise) as my JMCs now?

It seems Panalfo is the fan choice on this forum. I am just not too knowledgable on the gains of modding a high powered and noise fan down to basically the same specs as my JMC. Any help would be greatly appreciated.

For your power supply, open it up, and the fans are just plugged in there.

BE CAREFUL not to touch or screw with any of the capacitors... Just upplug one fan, and close it back up.

u probably wont c much of a temp change imo (maybe 1 or 2 degress) which wont matter much sense u dont seem like an ocer just a person wanting a quiet comp....those seem like pretty good fans from the specs....as for the ps fans ones ive seen just plug into the psu, i havent seem any that are hardwired to the ps...

the more cfm the better of course, if the psu fans are annoying you, step up to 90cfm panaflo's, run them through a variable resistor to get them at the right speed you want.

For the psu, just slow the fans down with a pot as well, it mightn't be an idea to disconnect them entirely for the health of the psu

Thx for the replys. I am getting my Epox mb and P4-1.6A this week so I plan on doing some overclocking. I thought about the ps fan, I may not want to disconnect it to keep the ps as cool as possible.
