Just installed one of these, been running it for the last three days on an Opteron 146. Impressed with the performance but it seems to have sprung some sort of leak, I could see droplets of liquid thrown out by the fan on the side window of my Lian Li case.

Thought it was coolant from the heatpipes at first but, on closer inspection, it seems to be coming from the fan bearing so I reckon it's oil.

Anyone else using this cooler had a similar experience?
 
:confused:

been using mine for a fair few months now... never had a leakage... wasn't even aware it had any fluid in it :confused:
 
Yeah nikebee they use fluid bearings in order to keep noise down.

But saying that I have had one for 5-6 months no problems and have just put a freezer 7 pro in my other system
 
I've since removed the Pro 64 and replaced it with the stock heatsink (obviously stepping down the Opteron to stock speed and voltage). There were a few drops of the 'oil' on the mobo as well. Hopefully it won't have done any harm.

I've requested an RMA from OcUK.
 
someone had a freezer pro bust off one of the end caps on the heatpipes and spew liquid all over his motherboard a week or so ago. it was on these forums.


a q.c problem maybe?
 
Nah, its a problem common to all fluid-bearing fans. Generally it happends under PWM speed regulation, the PWM-induced vibration makes the oil the ferrofluid uses for suspension spew all over the place. When i was testing SilenX iXtrema they usually lasted about a week under PWM before the bearing was all shot to hell.

Keep in mind that now its gone youll get much increased wear & tear on the fan, because the bearing isnt working properly anymore.

Personally ive found good quality sleeve/ball bearing fans walk all over fluid bearing fans...

Pulse Width Modulation

Which modulates an electric motor's speed with full power spikes rather than a continuous lower voltage stream. Not sure why fans use it as they are low load but they're often used where a motor has a high load and low speed requirements as the pulses are at maximum torque so the motor keeps turning. For example I've heard of it used to keep model railway trains working at a crawl.
 
I've not had this problem, but i've seen fluid berings shot to hell many a time, and it seems to be the exact same thing...

cure?

run it off a molex connector and use a VR to regulate speed;
Don't use whatever fan-speed controller you happen to have for the CPU;
I don't think the Mobo's 3-pin connectors use PWM, so that should be fine...( unless thats where you're running it from atm);
hit it with a hammer.
 
I've recently noticed this with my fairly new AC Pro 64 also - only a few weeks old, noticed on the inside of my case side that it had sprayed oil and it had run down and a tiny drop on my chipset fan shield too.

Should i replace/rma ?

no

same on my mobo so i replaced it with water cos i didnt want oil all over my new pc

water?

oh dear, you do realise that water + mobo = short, right?
