If the temps were better the other way, I still would keep it like this because I am more about appearance, and i don't think 40°C to 42°C max really matters.
I agree that a couple of degrees c doesn't make much difference. Of course, you have a kW power supply, and I'm using a 750W supply, so my supply may be operating closer to max temp than yours is. In that case a couple of degs c may make a difference. However, you've given me an idea to look into perhaps modding the power supply case to add a fan on the top blowing onto the circuit board from the back. It may or may not be worth doing depending on how much room there is between the pcb and the psu chassis, but if there's even 5mm of space I may be able to get a good air flow going on there.
Next time I take my case apart for modding, I'll pull the psu and have a look. Thanks for the idea.
I'm really sorry, I made you a long response with links to some great fan controllers and a little warning about the Aerocool controllers (function OK, nice looks but poor build quality) and somehow I managed to delete the entire response.
In short, on Newegg, the Scythe controllers are nice controllers, but are only 1 Amp per channel (12W) which is fine for a single fan on each channel. I like the scythe controllers myself, especially the one with the Vacuum Fluorescent Display.
There is a Sunbeam controller that's like 30W per channel, it's also aluminum and looks pretty sweet if you're into that. It's a popular choice. There is also a lamptron controller that is 45W per channel. It's also a popular choice and very functional.
Zalman makes a couple of OK controllers as well. Not great max amperage per channel (adequate though) but some have extra functions like a PWM channel (multiple PWM fans controlled from one channel), and one even has a wattage meter that will give you a reading on the total power your system is using. I have one on my other computer and it works great. It does have a sort of primitive control system though.
The Aerocool units (I have a Strike X) look awesome if you're into multicoloured displays and touch screens. I actually had to strip mine down (Strike X), resolder the output transistors and use thermal epoxy on the heat sinks because the company used hot melt glue and the holes in the board were not plated through wich caused two of the transistors to stop working.
They also have a Logisys that looks really interesting because it will control 3-pin or 4-pin fans, and has 36W per channel but I have no experience with that brand at all.
Good luck deciding.Edited by Mergatroid - 5/2/12 at 5:09pm
