I emailed their tech support twice over the period of two weeks, polite and informative posts where I outlined the problem (ticking and buzzing), when it took place (12V rail getting hammered doing dual instances of Prime95 etc.) and about every detail of my system components I had installed at that time.
Hey manalainen, interesting about 12V rail getting hammered, I haven't run dual instances of Prime95 etc, but I do have a K8T w/AMD64 3200, and ATI 9800 pro rig which does pull a lot on the 12V, and I haven't noticed any ticking and buzzing when playing e.g. Farcry @ 1024x768. If I have time over the weekend I may have to try with Prime95.
Unless I'm just lucky with my Tagan!
