Case/casefan question.

[Lionfish]

I know how we all love the sound of our fans

Opinions wanted for case fan selection.

4 fans or 2 fans, 80mm or 120mm ??

Sunon 80x25 36CFM 3 pin

Thermaltake 80x25 37CFM 3 pin

Delta 80x38 68CFM 4 pin/3 pin

Y.S Tech 120x38 131CFM 3 pin

Thanks.

Large fans are best, I suggest using only 120mm's if possible. The 68 cfm 80mm Delta is a very LOUD fan. As is the 138 cfm 120mm YSTech.

From a noise standpoint, two ~70 cfm 120mm Intakes, as well as two of the same for Exhaust can't be beat. Siting 2 120mm's for Exhaust duty is no mean feat. Intake isn't a problem!

Low RPM is best, and bigger fans like 120mms move some air--even when spinning slowly.

If noise isn't a consideration, there are many huge fans larger than 120mm PC fans. Huge fan, high rpm, it's hurricane time! And earplug time, too.

HEHE, you must be kidding

What did you say ?

[cloasters]

Yes I am kidding, at least for me. Some maniacs mount 12" plus fans in their left side covers and blast away.

After a three month vacation, I'll need to listen to a Delta Screamer again. Oh man. I am so not looking forward to it. Oh well, if I can find a ~33 cfm 60mm, that'll be much better.

Truth be told, the Sunon 108 cfm 120mm's are darn near as loud as Delta 38's. The Sunon's create white noise. Not the little banshees from hell, though. Two years of Delta 38's is too long. Where's that credit card?

cloasters,

Need opinions too.....I have a Lian Li PC65......

Need help in deciding if I should place (2) 80 mm exhaust or (2) 120 mm exhaust on the top???

Im looing at the 39cfm 80mm Enermax and the 84cfm 120mm Enermax.

Thanks.

If enough space is available or can be created, 120mm's are the best. With 120mm's you have the choice of moving lots of air through your case---or having plenty of throughput, but quietly.

Some cases come from the factory with two 120mm fan mounts. The Yeong Yang Lunar 5402 has them. One intake and one exhaust in the right places.

If you haven't cut aluminum before, be careful. Even though it's much easier to cut and drill than steel, it binds on drill bits like crazy.

Alrayty!!

Thanks cloasters

Using a Workstation/Server Tower, I'm using 3 - 80mm Enermax variable speed (with screw adj.) that I have controlled by one knob by joining them all together as one, and using an LM317T VR and a 5K Ohm pot.

I slow all the fans down in the morning and evenings, crank them up during the day.

I, too, was a victim of Delta Noise abuse. Now, I can even sleep in the same room while it's running. I love it.

My system temps sometimes reach the high 20's C
My cpu has seen 43 C while playing Unreal T for about an hour or two during the afternoon.

At the moment, about 9:30am, with all fans at low, my system is 24, cpu at 35.

Life is good.

Steel is a PITA. When I cut my blowhole in my case the thing was jumping up and down and it killed my cheap PS.
