USB Audio interface ESI ESU1808

Recently bought a new audio interface for my setup as I no longer could live with the small 1-in 1-out behringer lowbudget interface :-).
After some research I decided on the ESI ESU1808 an 18-in 8-out USB 2.0 interface, I ordered it from Thomann.de and received it quickly.
After following the recommended installation procedure (downloading the newest ASIO driver from ESIs homepage www.esi-audio.com) I started playing around with Ableton Live and the interface - after about one minute artifacts started showing up in the audio (crackling and popping - the usual indication that the ability of the setup was not high enough) - however changing parameters on the interface (for instance chosing a new sampling rate or clock) sort of reset the problem and it worked for about a minute and then problem reappeared. Not nice :-(
Did some surfing on the problem and found out that the ESI ASIO driver does not have the best reputation - I previously have had great experience with the alternative and free driver ASIO4All and this was mentioned in one of the posts I found - so I installed this driver instead (from www.asio4all.com) and voila the problem was resolved - so my recommendation is: use ASIO4all for a ESI ESU1808.
It seems the problem has resurfaced however now the problem has been identified as being CPU temperature related.

No it seems not to be temperature related after all, but while struggling with new hardware I upgraded the ESI ESU1808 driver to the newest version 2.9.28 which seems to have been a mistake, I now downgraded to 2.9.15 and now clicking noises are gone again
