Yes, just your blocks corroded a little more and you will get build up if you dont use silver or some kind anti algae.
Still not recommended unless you have to.
Lightning struck and blew my router, 2 nics a switch and my motherboards ethernet controller.
I have a fish tank thermometer in the water so I can check it any time
well last winter I did as the water temp gets to about -4 or so... I had to replace my motherboard dude to lightning damage so its not insulated at the moment.
When cleaning my Gpu block I actually noticed corrosion on the copper base...
Hey folks, Finally time for an update on this thread!!
My fan on the tower decided to rust up and fail due to a small design fault allowing water droplets to pass through the fan if the system was running without the fan running.
Also...
wow sorry gents, forgot about this thread for ages!
My cooler still runs perfectly (actually took it to a lan). Kinda in need for a cleaning now TBH...
im still getting the water to ambient temps, and I dont even run the fan when I game...
I would say no, but you should really look into some support in case you bump a card and crack a slot clean off the board :-\
if its a test setup you should be ok, but for more than 1 day I would get a bracket to support your cards.
Cpu idle seems a little high for 22C ambient - maybe try a re-mount.
I got to agree with charlie, I dont think you have enough rads space in use for your clock/heat dump...
Is everything in one loop?
