I had a pinched tube some time ago. Happened when i closed my case, a tube got stuck.. I didnt notice, and used my comp normally for about 30mn.
Windows crashed with a BSOD, then i could hear strange noises coming from the waterblock. Those noises water does when it's halfway to boil.
I immediately shutted down the comp and found out about the pinched tube immediately. The WB was *very* hot, though it wasnt burning and neither the CPU nor the thermal paste did suffer. I just replaced the tube, let the system cool down and all restarted finely.
My WB is a DangerDen Maze2 and i have 1/2" tubing, and my system is totally closed (no res, no air trap). My CPU is a Tbird 1000/AXIA @ 1487.
For one the thermal inertia of a filled system seems quite high, and for two the DDM2 is big enough to sustain such a heat alert.
Couldn't say the same for pelt systems though... those could butn out quite quickly.
