Fan questions

post #1 of 5
Thread Starter 
Hello there. I recently clocked my i7 950 to 4 GHz with some OK temps but I'm looking to lower them further so thought I'd do some questions about fans



I got 3 Logisys 120mm Red LED fans in the top of this case as exhaust, but one doesn't want to blow with an extender, I thought you shouldn't lose a lot of power from extensions? It gets power because you can see the red LEDs in the corners lighting (and yeah, its not the light from the other fans). The fans and my extensions have both Molex (I think I typed it right) and 3 pin, using 3 pin right now or would anything else work better? Also is Logisys a good brand or should I get some other fans like these: (I know it's a norwegian site) http://www.komplett.no/k/ki.aspx?sku=623871 ? They seem quite noisy and don't really know how I can estimate air flow by my hands because I'm not very experienced with PCs, but I'm not utterly retarded either

I'm getting my Rampage RMA'd so I think I can get the 3rd fan to a 3 pin (the H70 rad is in the way now) when I rebuild it, but it's still like 2 weeks until I send it back so would appreciate (vacations and stuff, huge LAN party so have to wait!) sorting it before Also if you can look at this section: http://www.komplett.no/k/kl.aspx?bn=10464 could you look for some ok fans? I know it's all norwegian but just look at the name and stuff, you should be able to get a pretty good idea, sorry I'm a bit difficult to help but norwegian sites seem to not have everything that the good stores have so would appreciate if you could try to find some good ones that my store got

Edit: If I didn't specify, I'm looking for 120mm fans

That is strange. Have you tried connecting a different fan to the extender? Is it a bad fan or a bad extender?

Also, most motherboards only supply about 2 watts to the fan headers (total). If you have a lot of fans connected you may be overtaxing the fan header.

As for fans:
They have three things that you should look for:

CFM (Cubic feet per Minute)
In Europe air flow in usually specified as Cubic Meters per Minute)

Noise, measured on db (decibels)

Power consumption (Note, most fans draw twice their rated power when they are starting up).

Here's a link (sidewinder) to a site that has a "listening room" where you can play the sounds of various fans and compare their relative noise.

Bin them Logisys. Get Delta fans.

When I let mine Spool they make a racket, but i put headphones on, i see a 12*C temp drop on full load. Best $25 I've ever spent (had them imported).

Thanks for the help, I'll probably order some new fans soonish then. It's probably either the power limits on the motherboard or the extender, but I dont understand why it shouldn't supply the same power (or almost the same) as it pulls from the mobo (and it does give light). The fan was working yesterday when I plugged it in a molex pin from the PSU, was at a LAN party so noise didn't matter, no sleeping family!

I'll probably get something I can put on the molex pins from the PSU without deafening myself

PS: I have 2 exhaust top, 2 H70 fans + H70 pump and 2 chassis fans from Corsair (stock fans) in the bottom, the one in PSU chamber and the one blowing on hot-swap bays. I dont think that should be too much or am I failing?
