MadDogMe,

I've never yet had that rad hooked up in a system. I bought it and did the inlet/outlet mod then sent it to Bill Adams for that test. It's still there as I don't need it yet and if it is of any value to him for testing for the Sim that's great. And when it's of no more use for his tests, or gets in his way he'll ship it back. Or if you havn't seen the info on it, it's posted in the Sim development Forum under the thread, "Radiators and Fans", some good info in that comparison of Sense87's dual pass rad and the single pass 2-342 rad. The single pass came out pretty well.

As to the pump I'll use it won't be a MD-30-20. From all I've been able to learn (many thanks to BillA and others) it would add more heat than that heater core can use. There is a post in the thread, "Look at this pump", where Cathar posts information on his MD-30 hooked up to two large heater cores and the pump adds so much heat that even with two cores he gains very little. As the 2-342 single pass I'll be making use of is only about 1/2 of his set up the MD-20 would be workable but wouldn't offer me much extra for the added cost, and I'd have to pull a hard drive cage to fit it. And according to Bill it would have a noticeable increase in noise level. I havn't turned away totally from the idea of a MD-20 as it would offer a increase in performance if I got it set up just right, but not but not a real big performance gain for what it would demand in costs, space, heat & noise.

As the MD-15 will cost less, take up less space, add less heat to both the water & air inside of my tower, it's looking pretty good to me. The MD-15 will still offer the dependablity and long life of a Iwaki. Won't offer a super flow rate like a MD-20 or 30Z, but still quite strong compared to most.

The rad shouldn't be a problem. That is the reason for the inlet/outlets on diagonal cornners, it makes flow resistence in all the tubes about equal. So you shouldn't need a extreme pump to make it work just fine. One thing I've gotten right at least.

I made up my mind to take my time last summer and try to learn all I could before I built a new system. I'm very glad I have. Had I built then I'd be looking at the nForce boards and Barton chips and be sad I hadn't waited, or working my a$$ off on O/T to build yet another system.

I've waited a long time, but now I feel I'm pretty well ready to start buying. I have the rad & will be ordering the tower and DVD & CD drives soon, along with some sound proofing foam to line the tower with. Will order the motherboard, Gfx card, sound card, RAM and hard drive only after all the rest is here and ready. Hope to get the best possible system that way & at best cost. But if I'm able to swing it all, it will be by far the best system I've ever had, and will be one to keep and upgrade as I go along. No more completely new built systems for some time.
