Pump buzzing and vibrating. Help? Updated with Pictures!

post #1 of 37
Thread Starter 
Hi,

My MCP655 suddenly created a buzzing sound. I've been running my loop for around a week now and I am pretty sure all air bubbles are out I dont see any and I've tilted my loop in all directions. It buzzes on setting 5 but when i lower it to 4 the buzzing stops. a few hours before it didn't have this sound not sure what could have happened.

Any idea what might be causing this? and how to deal with it?

edit: I left it to speed 4. Would this have any impact with my loop? or is the performance more or less the same with 5?

Loop: res-pump-480rad-gpu1-gpu2-mb block1-mblock2-cpu-RAM-360rad

Edit: Here are a few close up pics. Can anyone determine any significant damage?

lubricate the shaft.

No troll, do it.Try and take of the housing and lubricate whatever can be lubricated.
If you're sure there aren't any bubbles.

Just the shaft? it shouldn't. don't take the whole thing aport unless you know what you're doing. Just take of the cover and see if you can access any moving parts from their, lube them.

Is it running at full speed? (some can be throttled) if not, try and give it a couple of mins at 100%, maybe it'll shake it off.

Will put some lube when I break down the loop in a few days. I hope thats just the case since its been only a week since I used this pump.

Right now I left it to speed 4. Would this have any impact with my loop? or is the performance more or less the same with 5?

Is this new? I suggest returning it and let them deal with it, don't risk voiding warranty...

Does it still buzz on setting 5 if you hold the pump (to prevent vibrations)? I haven't used a 655 but a 355/35X can be fairly loud if not mounted with some sort off device or cushion to prevent vibrations.

^yes it still does. I mounted it with the neoprene padding included in the stock mcp655 and bolted it down. At first I thought it was the bolts creating the sound but I removed the bolts and now its mounted only with the neoprene and it still creates the sound frown.gif
