The 3M thermal tape that comes with the TBan makes a good job, provided you don't ask it the moon. Some things to keep in mind:
1) Clean well both surfaces before attaching the probe, using e.g. isopropylic alcohol or something that doesn't leave residues behind.
2) Choose the attachment point wisely, ideally you should pick the hottest point, but you also have to pick one that is easy to work with, it isn't in the way, and where there's enough space for the cable.
3) Route the sensor cables cleanly through the case, using twist/zip ties to make sure it's never in the way. This way the sensor won't risk being pulled if you need to work a bit in the PC, e.g. replace some card.
4) Fit the terminal part of the cable so there's minimum strain applied to to the thermal tape (ideally there should be none, but that's hard to achieve), or in the long run the sensor WILL come off.
5) To offset any strain on the sensor itself, add extra tape (e.g. duct) or twist/zip ties
6) You want to keep the extra tape down to a minimum, as for most tapes, the glue will decay over time and become hard to remove. Also do not apply the tape directly on top of the analog probes, or you risk peeling off the protective film when you remove the tape.
7) Stick with analog probes, they're much easier to work with because they're thin. Digital sensors are more bulky so they are better for the easy spots, e.g. HDDs, PSUs, or intake air temp.
8 ) Unless you really need them, don't use the yellow cables, those are used to feed back the fan speed data to the motherboard.
9) When you're done configuring your T-Ban, you can monitor the temperature and fan speed data using a small app like OpenHardwareMonitor (
clicky). Don't waste your time with SpeedFan, it's slow, ugly, and doesn't support the T-Ban, and as far as AMD/ATI parts, they are not supported properly, and in some cases, not at all. In a word: it's c***.
10) Take it easy, most people find installing the T-Ban a bit tricky at the start, but with some patience you can achieve great results.
