Full drain or top off?

post #1 of 6
Thread Starter 
Hey everyone, i installed a new VPP-655 6 months ago. Its time for maintenance as the reservoir has gotten a bit low. Should I just top it off or is a full drain reccomended? Also since the reservoir is not full could this cause the pump to make a louder than normal hum and vibration?

The rule of thumb is to drain, clean and refill a loop every 6 months or so. I usually just keep an eye on the res and fluid. If everything looks clean enough and I don't have any cooling performance degradation, I usually wait for a cleaning at the 1 year mark.

If you have fluid levels dropping in your system, fluid could be leaking somewhere. You should do a thorough check of your system. If you are using clean coolant, try wrapping each fitting in a piece of paper towel or toilet paper, running the system for a while and looking for wet pieces. Evaporation could cause fluid levels to drop, but the most common reason is leakage.

Generally speaking, slightly reduced levels in the res shouldn't cause hum in pump, but it really depends on your setup. If you have a small res that feeds directly into your pump, and the low levels are feeding air from the res to the pump or creating a vortex inside the res, this could cause noise from the pump.

A leak on or near the pump intake can cause air to be sucked into the system.
This might also leak when the system is off.

Well worth doing a thorough leak check.

You should only lose a little water over time. My current system has been running for 4 about years without a top up, although this isn't best practice.

Is it misleading me that everything around the pump is bone dry?

Noisy pump just means 2 things:
1. it's still working (or at the very least spinning)
2. the impeller is grinding against the walls

Now, impeller grinding against the walls can be caused by an air bubbles that is destabilizing the impeller.
Another possible cause would be debris going into the pump and getting stuck there.
Or, it may also mean that the bearing is already on it's last legs and you need to get a new one soon.

Is the noise a constant thing?
On/off throughout the day?
Only noisy on the first minute the PC startup?

If it is producing noises that is out of norm, I'd say just get a spare ready and open it up as soon as possible.

Its not very loud just a steady hum i never noticed before. I suppose it could be air since the reservoir is no longer completely full. When I get the chance I will try to record it's sound.
