I'm grinding over the MB specs and i dont trust my abilities to make the call if it can do it all on its own. Im sure it's because I have never dealt with controlling fans and sensors before. From what I understand when I plug a fan into the MB, it will be detected and I can control the rpm manually or be bound to a sensor for different tolerances, can the MB support several temp sensors on its own then bind the fans to the different sensors? I can see the TMS-EB205 with the expansion card can support all I need for sure and it supports a pile of temp sensors so I suspect that it can be flexible with assigning fans to different sensors right?
I am happy with my TMS-200/TMS-EB200 setup (I have one version behind current - difference is 10K vs 50K Ohm sensors) but there are a couple of things I would note about it:
1. The board reads off of it's own sensors. It doesn't get CPU core temps directly from CPU sensors like coretemp etc. You need to tape a sensor under the cpu block (but not in block to cpu contact area) as described in the TMS-205 manual. In the software there is an offset for each sensor so you can manipulate the reading to match what coretemp is showing but this method isn't perfect as temps fluctuate. When I was running a CPU only loop there was a substantial difference between the "TMS" CPU temp reading and the Coolant temp reading.
2. Since I added a pair of water cooled gtx 590 cards I found that the "TMS" CPU sensor reading stays pretty much in step with the Coolant temp reading.
I purchased this setup so that I didn't need "dial-type" fan and pump controllers in my case bays, so I could adjust and monitor everything in one interface, and because I thought it was cool
In the end I find that I leave the pumps on one setting and manually adjust the fans depending on load, ambient temps and sensor readings.
I would buy this (TMS-205/TMS-EB205) again but you may want to try some of the other members suggestions if you want to tie events closer to the true CPU core temperatures and/or save a bit of money.
Edit: Yes you can tie fan speed to different sensors. You can see it in this interface example:
There looks to be more ability in the current version of the software. My interface shows more options than the pic noted aboveEdited by Tuthsok - 11/19/11 at 8:09am
