Will MCP655 heat up liquid?

[Enz0man]

Hey guys. Me and my friend are building a computer and were running a custom loop for the cpu. However, all of the fans that are on the radiator are plugged into the motherboard, and we are jumpering the psu to leak test. So the motherboard isnt getting power which means the fans arent blowing air on the radiator. My question is, without fans, will the pump itself heat up the water enough to damage something? Do i need to run atleast 1 fan while leak testing? The rad is an xspc 360mm thick radiator.

Personally I would run at least one fan yes. Just plug it into a molex adapter, assuming you have one layin around. If not, not sure how you should power it.. lol

Ok thanks.

Yea, the pump doesn't produce that much heat, but it does, and it isn't negligible. If it is plugged in for a long time, without a way to dissipate the heat, your loop will warm up and could harm the pump. If the rad is in a very well ventilated area where it can get a lot of passive cooling, it might not be a problem, but honestly it isn't worth the risk, especially if all it takes is to pop a molex adapter on and screw a fan on.

Yea because we are gonna do a 24hr leak test. So by the sounds of it, that would be long enough for stuff to get toasty.

ONLY ddc pumps produce heat that will kill them.

mcp655 is a d5 it does not produce so much heat.

I would still hook up a fan, better safe than sorry. It is such an easy thing its worth doing. You do have a 360 rad, so it has good surface area for passive cooling, but why not just plug up a fan to it. Worth the 2 minute hassle in my opinion.

I've never had isues with my D5, Fanless.

I agree with him

 

Especially when you are dealing with expensive pumps and electronics, I wouldn't want to be bashing my head when I discovered that my dead pump could have been saved by just plugging in a fan, even if it is unlikely.

I would always hook up at least a passive radiator during a leak test with the pump running. I've seen a D5 overhead with no radiator in the loop (was my bad...)

Thanks linus. Huge fan btw.
