I'm new to this forum and also (prety) new to modding. anyway, I have big plans with my case and one of them is to build my own rheobus to control my case fans. Couple of questions: *My PSU is an Enermax 430W and the thing is that this psu has some kind of sensor in it. To make it short. My cpu fan is hooked (with the 3 pin connector to the mobo) and the psu aswell. Does this mean that the psu controls the speed of its own fans? (couldn't find it in the (crappy ) manual.) To make things more complicated, my main board is an Asus and they have something they call Q-fan technology. This I have currently enabled. So, in other words, my psu controls its own speed + Q fan controls the speed of the CPU + the PSU???? * Now to my actual question. As I said I want to build my own rheobus. I have read a lot of tutorials about it but can't find one which is really clear. Is it correct that all the casefans should be put in parallel, connected to each other with power cables? Also I'm not that familiar with electrical circuits, if I would put anything wrong together; would it just not work or would it blow up eeek or damage any of my other hardware. Thx for any replies and my deepest apologiez for my crapy English.
Welcome to the forums. I'm not even going to attempt to answer your questions about rheobuses...cause I really am not qualified. But about the sensor on your PSU....I have the same PSU. If you are talking about the same sensor I think you are...it is actually attached to the 80mm exhaust fan in the PSU. It is a temp sensor. It's supposed to cause the fan to speed up or slow down depending on the temp, pretty much like a thermaltake smart fan. I think it is probably more of a marketing ploy than anything. According to Motherboard Monitor, that fan was always running at a constant (fairly high) rpm anyway. I actually replaced mine with a red LED fan. So as I understand your Q-fan stuff on the mobo..it would be controlling the cpu fan and the PSU exhaust fan.
idd so I guess it would be best to turn of Q-fan, let the PSU do its thing (with or without speed control) and if I would succeed in building a fan controller I could attach the CPU fan to that one aswell ... or not
From what little bit I know about these things (which really is just a little...I have built a small simple rheobus once) you really want to be careful putting a CPU fan on a controller. If for reason you turn that fan too low or off or it fails....it's bad for the cpu. Also, I think some motherboards may have logic to not startup unless a fan is plugged into the CPU fan header. Like in my case, I have a hsf that has the rpm wire only plugged into the mobo header and then the power plugged into the PSU. I'm not familiar with Asus boards. So I can't tell you about that.
