Hey,

I'm about to go pick up a 120mm Yate Loon high speed fan at Microcenter tonight to replace the busted fan that came with my Tuniq Tower 120. My question is while I'm there, should I pick up any additional fans for the CM 690 case the Tuniq Tower is in? I know there are spots to mount additional 120mm fans, one on the bottom two on top, but wasn't sure if this would make any real difference or not. Also seems like it might make flow more turbulent.

One thing I was considering was replacing the back fan with another 120mm Yate Loon high speed fan, to match the one on the Tuniq Tower. Since the Tuniq Tower will be pushing 88cfm of air at the back fan, it made sense to me that the back fan should also push 88cfm. I could then mount the current fan on the back either on the top or bottom. Would you recommend this, and if so where would you put the now extra fan?

Any other suggestions are welcomed. Thanks!

the fans that come with the case are mediocre at best. if u dont overclock or whatever, it could be enough. but if u plan to over clock, those wont be enough.

theoretical airflow should be low => high.. if i were to pick.. (yate loons of course).. all high speed yate loons but controlled by fan controller. heres what my settings would be..

med/high on front, med in 5.25" bay, low/med on side panel and bottom. high on top and rear.

its best to get the highest cfm one for ur tuniq. considering its just 1 fan inbetween two towers of fans. its going to need to pull air thru and push air out. by the time it goes out of the heatsink, ur going to need a high cfm exhaust either above or behind it (depends how you are going to mount your tuniq..)

*edit*

just got my freebie ocn applique from rolandooo's freebie drawing.

looks sah-weet! dam now i may need to put one on everything with a see thru panel @_@

Thanks for the response. Of course I'm overclocking, this is OCN after all. I've overclocked just fine in cases with far less airflow than the CM690, I know the current setup will work, but adding more yate loons might allow for those extra few MHz. At $12/pop I'm not going to be going crazy with them, but was wondering if the scenario I laid out above made any sense (putting a yate loon on the rear exhaust to match the power of the yate loon being put inside the Tuniq Tower). I have no idea how much air the CM690 fans move but I bet it's closer to 40cfm than to the 88cfm of the yate loon. That means the air being pushed through the TT probably won't all go through the exhaust fan and some might get recirculated.

A top fan above the TT (near the back of the case) seems wasteful, possibly harmful, as I want smooth laminer flow going front to back of the TT. I was thinking of putting another exhaust fan on the other top mounting spot (the one closer to the front of the case) but this might create turbulent flow with air being pulled toward the TT and also toward the top. However, it would create a low pressure area by the intake of the TT which could help. Too many variables for me to know for sure, that's why I'm asking you guys that may have already experimented with fan placement if you think it's worth it.

12 bux a fan? its 3.50 each on jab-tech!! i like have the fans around the heatsink.. of cos not as powerful as rear and heatsink but its to help pull out the heat from the northbridge, etc.

Yea, $12 each at Microcenter (at least according to their web site, we'll see how much they cost in-store). Unfortunately I need at least one by tomorrow so I can overclock the rig this weekend. I suppose I could order another 3 off jab-tech and install them on the case early next week. I'll probably just do that, a high power yate loon on the TT, two on the top exhaust, and one at the rear exhaust, then the CM fans on the side panel, bottom, and front as intake.
