Pump Cooling

[Alaric_2000]

I'm struggling battling high case temps. I'm attributing much of my high temps to my Eheim 1250. For example, I'm seeing temps, as we speak, at 31C inside mah case. I have 2xPanaflo 80mm H1A's@7V, and 1xPanaflo 92mm H1A@7V doing exhaust and I have two Panaflow 120mm H1A's @ 7V doing intake thru my rad (push-pull). When my PC is off and just the pump is running, I turn it back on and I see case temps as high as 35C. I want to keep the pump inside the case. Any suggestions?

TIA!!

try one of these:

It's a relay for your pump.

I have a relay, but I didn't want to install it. I'd rather keep the pump running. I just think it's contributing to higher case temps even when the system is running.

you could duct air out the case from around your pump.

how about some water-blocks for yar pump...

is precisely why I absolutely love submerged pumps, they are not only smaller, but run quiter, and more powerfull, and they are liquid cooled.

Hi #rotor. Nice to see you around. Hows it going in the GWN.

I'd insulate the pump from the air in the case. That way the coolant in the case pump will absorb more of the heat.

I know someone will say something about it overheating, but this shouldn't be the case. I've seen people run Eheims wrapped in towels (nice and quiet) for extended periods of time with no trouble.

True, but the heat must eventually go somewhere. If it doesn't go from pump-=>inside air then it goes pump-=>towel-=>inside air, and you've acomplished nothing.

Is there any way that you could vent the pump after the rad?

Otherwise, I'd consider figuring out where exactly this inside temp probe is located. That would probably be a good clue.

Hey... I KNOW exactly what you mean! I bought this ViaAqua 1300 thinking it was going to be quiet and to itself... WRONG! While it's a nice pump, it has this damn annoying Huuuuummmmmm that get's even more amplified when I close the case, even when I've got it atop a ton of bubble wrap! Then there's the awful amount of heat the dang thing radiates! It's a nice pump, but not all that it's hyped to be...

Any how, I'd recommend you change you're setup so that the pump is near the incoming air from the front of the rad. That way, the incoming air will cool it down, which lessens the increased water temp and aids in over all cooling... Other than that... you could make a submersible res for it, your radiator SHOULD be able to handle the increased water temp from it, it's only a few 10th's of a degree more it will have to deal with. Plus the water will serve to dampen the noise (if yours makes any) and space will be saved. HAha sounds like I should take some of my own advice! Good luck!

Thanks for the killer advice guys. I might just make a duct from the pull fan and over the pump and right out the back.

...or the bottom...?

true, a submerged pump is watercooled. that also means that you are adding heat directly to the water. this will help keep the CPU nice & cozy. an inline heats up because most of the heat is not dissipated into the water, but into the case air (unless you like heating your water & decided to wrap the pump with a towel so the heat has no where to go but into the water). i use a small fan at roughly 1/4 speed (PWM controller) to cool my Ehiem 1250. the below pic shows how simple this was to do with a plastic duct in my Antec.


as for vibrations:
an inline pump creates the same level of vibration that a submerged does (sump pump). the difference is someone that uses inline must be creative about how to isolate the vibrations from the case. a submerged pump has water to damp out vibration, but an inline pump must use soft mounts to do the same. i personally think a nicely mounted inline is as quiet as a submerged, more efficient & better looking. here's how i isolated my 1250 with some interesting hardware i found at my local Ma 'n Pa hardware store:


as for the relay:
why not use a relay? it will save you hours of unecessary wear & tear on the pump as well as save a bit of energy. not that i'm even close to being an environmentalist, but if i can save pennies with little trouble, why not?. the top pic shows my relay socket box. besides, a pump relay adds to the technical feat to any PC.

nemaste: how are the plastic clamps doing vs the twin zip ties ?

smaller, mostly. quieter....depends. more powerful?? right...liquid cooler; they all are. water flows in the housing and around the impeller (on mag-drives at least); this is what cools them. thats also why its not good to run them dry for any extended peiod of time (they'ld overheat and burn out).
