Might be a great addition to the fan section MasterKromm. You will have to give me some time (maybe another week) to get it all in and pretty. I am getting married this Sunday so revamp incoming soon. Any additional info that you want to provide would be appreciated.

Thanks again +rep

I have a silly question about case fans. I'm looking at getting 2 of the San Ace 120 109R1212M1021's. The specs are on this page: http://farm4.static.flickr.com/3432/...9d8357e8_b.jpg

I can't see if this is an exhaust or intake fan. Can I just turn them whichever way I want them to face and still mount them? I've never used aftermarket fans before so I'm clueless.

Also, my motherboard has, besides the CPU PWM fan header and the north bridge non-PWM fan header, 3 more fan headers for case fans-- 1 PWM, 2 voltage-modulated. Can I assume that the mobo will still ramp up and down the non-PWM fans the same way it would the PWM fans under load, as long as they are hooked up to the mobo's voltage modulated headers?

Finally, can I daisy chain fans hooked up to these headers or is that only for fans hooked up directly to the power supply? I want to hook up more case fans than just the 3 the mobo supports (top, back, side, and 2 front, so 5 total) and need to find some way to keep them quiet at night (no load.) Daisy chaining them to the mobo would solve that problem because they would be modulated down.

If I add a San Ace 120 (non-PWM, I believe they all are) to my TRUE, can I hook it up to the voltage modulated fan header on the mobo and leave the CPU fan header empty? Or is the mobo gonna start throwing errors and refuse to boot?

All fans can be flipped one way or the other to be exhaust or intake fans.

In regards to how many fans you can put on your specific mobo you need to see how many amps/watts can be pulled from your mobo to power the fans (see your user manual or info online about your mobo) When you are talking about performance fans like the San Ace it is always better to plug them directly into your PSU. You can daisy chain the fans but do it only through the PSU because of the power needed.

Your mobo might get errors or fry your fan due to you attempting to pull too much power from it. In reality your best option is to get a fan controller. If your looking for something cheap then go with the base model Rheobus I linked. Read up on the fan controller section and it should be all the help you need for it.

I can't find that info in the product brief or technical specs:

Any ideas?

General rule of thumb (if not specified in the manual) when using a fan header on a quality mobo make certain the fan draws less than 1 amp... You're always better off using a fan controller or just running directly off the PSU. However,worst case scenario you damage the fan header. The mobo will still be functional otherwise.

@ shadowclock

I'll give it some thought and edit this post if I think of anything else worth mentioning...

I wish you happiness with both the wedding and marriage, you must be brave...

Each and every time I've ever heard the M word I've bolted. Honestly, it could be two strangers on the street talking and I'd still run. Heck it took me three days just to log back onto OCN after reading what you wrote!!!

(only joking)

i suggest someone finds the coolermaster hyper N620's reviews, apparently it's a bit better than even the 212+

MasterKromm,

I have added some info on bearings. Hopefully that will be enough general information for the masses to allow them to make the right choice. I don't want to go into too much detail as that isn't what my guide is about. Too much info and everyone will just TLDR (Too Long Didn't Read).

I took a look at that review for the Hyper 212...it looks quite a bit off to me. In the review at 3.8Ghz and 1.45v they have the Megahalem beating the Xig S1283 by only 5 degree under load. That is just impossible as many OCN members see a much larger jump than that in their tests. Has me very skeptical and I would like to wait for more OCN members to chime in with personal experience on that one.

Thanks again for your input and suggestions!

+rep for this, very helpful. So would it matter if Sflexs or Panaflos were mounted vertically or horizontally?
