To submerge or not to submerge...

[portorock]

I know some may be thinking "DUHHHHHH", but after reading a few threads, I decided to submerge my pump in my reservoir, and to my amazement, I lost 3 degrees C off my load temp. I'm surprised it took me so long to do this. Good luck to you future fluid coolers.

Each setup is different:

You put your pump in the reservoir and the temps go down then thats GREAT.:cool:

Some people temps go up from the added heat of the pump in the water (Which is my case) and run it inline and get lower temps.

The point is you have to do what works best for your setup and what works for one might not work for another.

D*mn, just wish I could get my temps as low as yours. Oh well, like you said, each rig is diff.

[Crappy]

Now if I could find a reservoir that could hold my Eheim 1048 and fit in my case. I would like to see the temps.


(note to self: Find bigger case.)

i havent compared, as i've only used submerged. but here's my question...

WHAT pump could put out enough heat to heat up a reservoir full of water?

i guess maybe i'm odd in using a large ammount of water in my system (about 1.5 gallons), but the way i see it... comparing my danner mag 7 pump's heat output to my 113watt tbird just seems like a drop in the ocean.

i guess i should take a temp reading of my water after the system has been shut off for a few hours, and then take a temp reading of the water when just the pump and radiator fan have been running for a few hours to compare.

once again, i've never tried, nor compared... correct me if i'm wrong. just seems strange.

Crappy, do you have any pictures of your setup?

If not, can you describe the parts and how you have everything positioned? Please include as many details as possible including your water mixture. I have the same radiator as you and my temps are terrible. My block is a Maze 2.

correct me if Im wrong but doesnt a submerged pump put out more heat thin a inline pump?


I have this 150 gph pump and I tested to see if the water gets hot over time and it does

in about 1 hour my water go almost as hot as bath water
and that was with a 150gph pump

Ok here are some pictures of the setup as it was when I started to now.

This is Stock BeCooling kit with Eheim valves added for filling and bleeding.

Same setup with a 4x4x4 reservoir and a Rio400 pump. all lines up to this point are 3/8"

http://home.nyc.rr.com/hardware/Picture3.jpg
Eheim 1048 with bleed valves and brass fittings.
All lines are now 1/2" but the rad and block are still 3/8" That will slow my flow down abit but they will be repaced soon with a DDMaze2 1/2" block.

Edit: I think the 3/8" street elbow going into the intake of the pump is slowing down my flow big time. I'll have to find another way to get it to fit in my case without.

The water mixture is 4oz of water wetter to 1gal of distilled water. and the flow of water is from
Pump ->Rad ->Block ->Pump

PC is in a AC room with a temp of 74.6f as of the time I'm typing this:
Case Temp is 24c
CPU is 24c

I have seen this sofar with my setup. The more water your setup holds, "inline or submerge" the less heat your pump will give off.

I might be out of my mind on this but I've seen a 2c case temp drop with 1/2" line over 3/8" and the pump feels cooler.

I think it's also depends o the power consumption of the pump, here is the specs of Mag-Drive

GPH WATTS
140 12
190 19
250 22
350 35
500 45
700 70

Damn my pump outputs 70Watts of heat, better use the inline method I guess

Crappy, thanks for the pics and details.

That is one nice rig you have.

Where did you get those valves?

Also, what do you do when you "bleed" the system?

And how do you use the valves to fill the system with water?
