The cascade went into my system yesterday. Leak tested about 3 hrs w/ no problems, so took the plunge and turned it on.
The following of course is totally unscientific and qualitative and not finished yet. Only change was cascade replacing MCW-5000 (swifty)and new change of coolant.
Using MBM as temp indicator when running Prime95 torture testing:
Old temps: system ~ 25-26c, CPU 40-41c
New temps: systme ~ 25-26c, CPU 32-33c
Using Shin-Etsu G751 so temp may go down over next 2 days!!
Will put up some pics in couple of days after burnin and testing and installing Photoshop.
