Hey. So I use Raijintek triton water cooler and my waterblock is currently plugged on CHA_FAN3. My question is... why does HW monitor show 4200RPM when max RPM of my water pump is 3000rpm @ 12V. I have difficulties plugging the waterpump, since I really don't know if it's okay that I plugged in on CHA-FAN3 (had it plugged on PWR_FAN before), but I didn't get a solid answer where can I plug my waterpump. (There was no 3pin-to-molex connectors included, so I can't plug it directly to PSU)

I tried CHA-FAN2 and CHA-FAN3 and they both get the same reading...
and yes, the RPM fluctuate from 4100-4300. Is it possible that pump is getting "too much current" from motherboard and maybe that's the cause to that high rpm reading?

No it isn't getting too much current as it will only take as many amps as it needs unless it is shorted and then it wouldn't work right anyway.

Since it isn't changing with different headers it is most likely a faulty tach sensor. Do you have any other fans on the system that report speed?

I have 2 case fans in case, but these are connected directly to psu. So no, waterpump is the only thing that's connected to motherboard.

Here you can see the specifications of the item: http://www.raijintek.com/en/products_detail.php?ProductID=18

Well without a fan you can't check if the mobo is just misreporting speed. There are only really 3 possibilities and none of them are much concern:

1:Mobo misreporting speed. annoying but not a huge problem
2:AIO misreporting speed. again annoying but not a big deal
3:The pump is actually running at that speed. Yay! they changed pumps for whatever reason for that run and you got a better one. This one is hard to tell because there are only like 3 or so companies that actually make the AIO's and everyone just rebrands them.

I really appreciate your effort to help me:) will try to plug fans on CHA-FAN headers and see what they report. Anyway, again... there's no chance that it's getting too much current and it might "burn" over time because of that?

I may be overreacting, but I got the same cooler 2 months ago, which unfortunately leaked so they sent me new one, so I just have in mind that something might be wrong with this one as well :)

Not a problem. and no the only way the pump would be getting more amperage than designed would be a short in which case it would have already been toast. If it does burn out at that speed it will be due to the design not its power supply.

I completely understand why you're worried though. I would be too after a leak.

I think its because you have a freakin' Raijintek watercooler.Altho,my Fractal Kelvin T12 is also running VERY fast,its not the fans,they are controlled by the mobo (It changes speeds according to the CPU temps) but the pump is running so loud that listening to airplane jets and intel stock coolers seems refreshing...Help?
