Bluefront's Monster Fan Project.....
Lately I've been depressed because of all the really big fans and cases becoming common. Well I determined to go these guys one better...with the biggest computer fan ever. This guy on Ebay had this 450mm fan pretty reasonable...it's a Thermaltake or SilenX, he said. It blows 950cfm @ 24db. according to the mfg specs.....
I got a case adapter on the way from NewEgg.....but I've got one problem. Should I make this a positive or negative pressure case? Oh.....what PSU should I get? I was thinking maybe 1500W. Any ideas?

When I tried it negative pressure, it sucked the MB out and blew it down the hall.....so I guess positive pressure is the way to go. I guess I need to slow it down a little. Think a Fanmate will be ok?
And I'm having problems with the heatsink fins.....they keep disappearing. Do they make heatsinks without any fins?
I can't wait to see what Felger Carbon will do to best this one.....

No it's a 12V fan, but the start-up draw is 15A, maybe 15W.....I forget. I guess the 90W PSU in this old case won't quite be enough. For now I'm running it off a truck battery. Humm....maybe solar power. I could set it in a window and it could do double duty as a window fan. Right......
Damn....this last Christmas present is making my head spin. Opps. Back to the fridge...

Actually I started out with a fan bigger than my case - I have two 20" floor fans and until recently I had never been able to mount one in my Evercase E3505. I have finally made the necessary breakthru!jaganath wrote:I warned Felger Carbon he would eventually end up with a fan bigger than his case...
Experimentation with Klein bottles and hypercubes showed increased promise. What's needed is an interior volume much larger than traditionally defined by the external dimensions. Finally, complete success: hyperdodecahedrons!
Now I'll show that blue charlaton what a real big fan is! And I'll mount it in a USB thumb drive!

Kidding aside.....this particular 12v fan is from a Jeep, the result of a big recall. The composite blades sometimes fracture, with predictable results.
I'd start to worry about this exact problem if computer fans get much larger. I can see myself patching a hole in the case made by a flying blade....

Kidding aside... if the 220mm fan is run at the same blade tip velocity as a 120mm fan, the noise level would be 6dBA higher and the CFM 4 times higher. In fact, 220mm fans in SPCR cases will be run with linear tip velocities substantially lower than the 120mm fans we're already using. So it's the holes from flying 120mm fan blades you need to worry about. Seriously!Bluefront wrote:I'd start to worry about this exact problem if computer fans get much larger.

Even Mike Chin seems to think that because the fan is big, it must consume lotsa power and vibrate like mad. Uh uh, just the opposite. My fan off a Kandalf side panel is rated at 12V .3A, exactly the same as a YL D12SL-12... and my fan will commonly be turned down more than the YL when used in exhaust fan duty.
