First a special thanks to Dryadsoul for the Bonnie bonus, I did some pressure drop testing of the heatercore and it's very good!

Here is the beast itself, the dimensions are 2" thickness x 6-3/8" Width x 10-3/4" Tall. The fins are really not as dense as I was expecting, you can see through it if you line it up, but it sure is thick.


I did my testing by streatching tubing over the existing barbs which is a fair challenge with the larger inlet barb, but it works. Putting smaller barbs on would probably give you slightly more restrictive results. I ran the test at my standard .5, 1, 1.5, 2, and 3 GPM ranges, created a second order poly in excel, subtracted the pressure drop of the manometers and tubing and developed the following curve.

Anyhow, the Bonnie rad is a good flowing rad, it's better than the MCR series and about equal to the HWlabs BIX series. It's still not as free flowing as the Thermochill PA series, but I was suprise to see it do this well.

I really do think these heatercores are much better than they get credit. They are thick, but they flow well and if mounted with a shroud to make use of the full width and if you used some good 38mm fans on them, I wouldn't be suprised if they compete very well with many commercial rads many times their price.



Long live the heatercore

Nice!

+rep, nice chart

I think you just indirectly solved the problem I have with the awful temps in my loop. My rad is too restrictive! (BI GTS240) Great graph too, shows the PA series as the king again, I thought the Bonnie might be equal to them, but I guess I was wrong. Still a nice performer though.

Long lived the king!

Very nice, but for the price. Bonnie is the best out of all of them

The Thermochill PA series are too expensive

Yeah, I hate it when people give me BS saying that the bonnie heatercore is an inexpensive alternative because it sucks.

It is inexpensive and it performs just as well. It is the smart alternative.

Thanks, but the real thanks should go to Dryadsoul, he donated the rad. I was initially thinking of using it for a third loop to cool the chipsets, but now I'm thinking I ought to give it a try on the CPU loop just to see how it does thermally.

But this was just a flow rate test, the only heatercore thermal testing I've seen is by swiftech when they were comparing several 120mm rads. One of the tested was a D-tek rad that is a heatercore cut down...it was fairly close to an MCR120 with the fans they used. A regular heatercore like this are much wider than a 120mm fan, so if you built a shroud that could utilize the entire surface area, it should do even better than that. It's probably equivalent to a HWlabs BIX 240 or somewhere in between a 240 and 360.

Thats a very nice setup and graph thing you got going on, thanks for sharing the info. Good job dude.

Great job as always !

Rep+ !

We may need to find some way to get a GTX in your hands for some testing.

Yeah the Bonnie is a little more restrictive then I would of thought...But dang she has the surface area and fins to cool well........


I'm going to do a pressure test on my 480 Joe when I break it down next month for Martin...I wish we could do a GTS to that figure is from some French web-site...

Martin I wish we could find a way to do accurate heat dissipation on these rads to...The only way I would know to do it is with a die to control the temp's and some expensive temp measuring equipment...We cant go by published CW because their is no standard..Is there a cheap way to do it?..I really miss Bill Adams doing CW work, but hey he has to make a living to....

Thanks Martin...Be glad when you get a chance to do the Stinger....Yeah I'd stick the Bonnie on the CPU loop to....I don't know if your putting out enough heat for it to really make a difference but it cant hurt......More is usually better...
