I thought of taking a picture when I first noticed it, but it didn't change much after that so I never did. I just assumed it was finer bits of paint/coating flushed from the radiator and black fittings, like the flakes I saw during the initial flushing. I have been occupied with configuring...

I first noticed the fine sediment in the reservoir a couple of months before the momentary burst of tiny bubbles on start-up began happening.

Here's an update since I'm currently servicing my Eisbaer Extreme Solo coolant system for the first time: After roughly 6 months running successfully as shown above I am completely rebuilding/upgrading my system this week. (reasons unrelated to liquid cooling) In that time the Eisbaer ran...

They spray the end caps, and the middle only gets oblique overspray. The company will have to chime in about the type of paint. Living in the tropics I understand the concern about corrosion. When I removed my 4 year old aluminum air cooler the fins had a bunch of crusty white oxide in some...

I haven't taken it out of the housing to check the setting, but I am expecting that it was set at 5 when it was assembled. When I run MSI Kombustor "CPU burner" the pump RPM goes up from 3800 to 4440 RPM, and then back to 3800 when I stop the burner, so maybe the motherboard is actually...

I put the pump cable on the CPU_OPT header, which I think is read-only RPM. (not PWM control) The fan cable is on the CPU_FAN header with PWM control.

The Asus motherboard software reports about 30-32C when not much is happening, but it varies quite a bit as different process start up. When I run MSI Kombustor "CPU burner" it goes up to about 71C. (4.7 GHz i7-4790K) I don't have any other stress testing software right now.

It is installed and running quietly, cooling my CPU only. The pump tach is connected to the CPU_OPT (read-only?) header on my motherboard, reading either 3800, 4000 or 4200 RPM on different days. I have no previous experience with water cooling, so I can't really say anything about...

I think that's intentional, for a more direct heat transfer to the air.

I got rid of the jug and closed the loop with a little rotary flow indicator at the end of the hoses, using gravity to vent bubbles and top off via holding its port as the highest point. After churning out some of the little bubbles for the first minute the unit settled down and ran silently...

I'm trying to fill and test an Eisbaer Extreme Solo I just got. (the pump/radiator unit without the CPU block) I ran tubes from the in/out ports to a jug of distilled water, using soft tubing and bulkhead fittings on the side of the jug. The results are not what I expected. Since this is...

Is the particular alloy of stainless steel chosen to be compatible with a copper cooling loop?

Quick release fittings 17223 and 17225 have a large spring inside each half of the fitting, in the coolant flow. What material is this spring made from?
