You need to place the heaters in a high flow area of the reservoir as well. You can also get inline heaters like Skinnee uses in his testing setup, only he has several hundred dollars of equipment to go along with it to measure pressure drops, airflow, etc.
Looking around at prices, this will still cost a lot for me to dump say 5k watts heat into my res.

Perhaps cooling capacity could be worked out by figuring out time to take say 5 or more gallons of boiling water down to below ambient? I don't know the math - or how accurate such a test would be - but it is a lot cheaper than the electric heaters.

Maybe if Martin or Skinnee were curious one of those two would have the stuff needed to determine cooling capacity.

Interesting but as far as getting actual formulas to play with from those numbers...

You need the heat going in (in watts) and the temperature over time to form truly useful formulas. Your method would be great for just playing with one on your own, but to do real tests it is a bit questionable.

EDIT:
I got my bong up a running last night and leak tested it overnight and obviously it is now running. I'm getting load temps on my Phenom 9850 around 35 but I am not convinced that is the true max so I'm going to hold off on a lot of numbers until I do a good, long burn test. But anyway, I'd like in the club and I'll post pics of my bong sometime later.

I think my househould water heater is ~3500w. If you could find one in working order.....you could possibly run you loop through it and the 2 circuits that it'll require....

Why are you seeking a 5Kw load?

Nifty. What are you monitoring temps with? Suggest OCCT as a stress test since it gives temp graph as well once finished. Everest is also pretty nice to monitor temps with while running stress tests.
Load temps of 35 on your cores are very reasonable on a bong. My tower bong held my e8400 cores to 40C while running Linpack. Don't know if I still have pic of temp graph. Will look.

The 5k load number was just something I figured would be a good test to highlight evap coolers capacity.

Re. your testing - I figure you have a lot of folding rigs set up and plumbed together. Was wondering if you could put them on your Volenti/Naja - by itself - and see what your water temps are after say a day of folding. Due to evap rate may need to add water/ run shorter test.

I got it to 35 with an hour of OCCT, after that I ran Everest and it's own stress test, then some Prime95 (but that was only for a little while, not a full run through). I have Everest, OCCT, Prime95, and Orthos (which I never use) for stress testing and CoreTemp for monitoring.

I did that. Check out my HVC thread starting at post 13. I just scanned it, but I let the farm run for at least 2.5 hrs on the HVC only. Any system is going to reach equilibrium....after that it's just going to fluctuate with the ambient temp. Unless there's active cooling like with my chillers. I estimated ~800w, but it's probably more like 900w. 1Kw today, and will be more once I get these new cards under water.

The more you put on these systems--the better they will perform: The greater the delta between water temp and ambient temp--the greater or faster the heat removal.

Have fun trying to generate 5kw of heat. That's a lot of juice! Best bet would be the stove, but it'll take 40 minutes to boil 2 gals of water. Better check the temp limits of your pump and tubing!!! But you don't really need to boil water. What I did originally was add 4 gals of hot tap water, noted the temp and then the time it took to get it down to room temp or below. It's somewhere in the beginning of the HVC thread.

I am going to start a post build, build log. True, I don't have pics of my bong while building, but what was there to it? A little piece of pipe, a 90 degree elbow, a little piece of pipe, then reduction to 1/2" barb. The main tower is slip fitted on and there is a fan hooked on the sanitary T with tie straps. Really nothing amazing. But I can post the temps there and how it does on evap, etc.

Anyway, I BSODed after about 30 minutes of Prime95 at 2.9 Ghz at 1.4 vCore so I am trying 1.41v.

UPDATE:
I am now running my Phenom 9850 at 2.9 Ghz on 1.425 vCore (it will not hit 3.0 even at 1.5v). The system has equalized after several hours of Prime95 at about 43 fluctuating between 40 and 45.

This is not bad temps. Possible you will see better if your TIM has not finished setting up. What TIM are you using? Also worth ttrying a couple remounts.
Looking forward to the log and pics.

Full load temps are still in the low 40's. I am using Shin Etsu X23 and I am pretty sure it has already set up and the mount is good in my opinion. If I ever get around to building a really strong backplate I will play around with remounting then. It looks like I'll have to top off daily and I'm estimating maybe a quart a day (18h, heavy load). I could go longer but the way I have my bong setup it gets louder when the water level drops and is rather annoying.

As far as the OC, Stable - 2.8 Ghz, 4.125 vCore. I hit 2.9 and it would boot but could not hold up to a long Prime95 or OCCT test. I went all the way to 1.5v but no luck, I played with slowing down RAM (still needs to be fixed, as it was at 1122 5-5-5-15 2T). I will keep fine tuning to get more out of the memory but that's about all I can do with it until I get a PII 965.
