I'm having a very difficult time finding an acceptable fan controller as well. I had not discovered this Lamptron series, but generally with fan controllers from what I can see a lot of them are unreliable and not very robust.
I'm trying to find something relatively specific, yet not out of the blue:
1. Simple design
2. Displays all 4 (or however many) temps with individual knobs for control
3. Displays all 4 fan levels (in RPM or %, I don't really care which)
4. "Warning" system to where if I didn't turn a fan level up to supply adequate cooling for a CPU/GPU that it would warn me via a beep or blinking system.
5. Robust
If possible, it would be nice to have an auto and manual switch. Auto being a programmable feature in which I can set a temperature vs fan speed profile. I know SpeedFan can do this, but I've had difficulties getting it set up.
I know this seems complicated and I'm probably asking for something that may not exist since the market for a "control system" cooling for fans in a computer is probably not very wide, so who would waste the resources putting so much time/money into it when not many would buy/use it?
If anyone knows anything, it would be much appreciated.
Edit: I'm MOST interested in an external fan controller so I can sit it on my desk. the NZXT LXE has a great unit on the exterior and would be great if it wasn't HIGHLY unreliable. It's the only one I can find that looks half-way decent, but if anyone knows of any that I may have missed, please point me in the right direction!
Thanks!
