I'm just a noob too, but my impression is the opposite--that folks tend to use heatercores with high CFM fans. Can someone enlighten us?

Hey Freddy,

So do you think heater cores, on a size-by-size basis, are more efficient than radiators designed specifically for PC cooling? That would surprise me, though I've been surprised before.

Yes, heater cores are more efficient. They're generally allow for more free flow, also. Not only are they more efficient, they're generally larger. So you're getting help from both aspects.

Heater core.

Yup low speed is cool, I have variable speed fans and never turn them up, I have experimented with running them at high speed and the difference is barely noticeable if at all, as long as you have some air flowing over a heatercore, you are good. I have run four hours with no fans running and no problem.

DrDeville

Interesting--I'd love to go passive. What size core do you have?

Heater core tubes are extremely thin. If you have ever repaired one, (we used to in the old days) you would see it. Remember they are only designed to work at 15 to 20 psi, If I remember some of the PC radiators are tested at much higher pressures so they have to be made heavier.

I have the 77 bonnie

Thanks. You've given me food for thought. I was about to buy a Black Ice Pro III radiator, figuring that since it has a little more area than a Bonnie core, and is designed specifically for PC cooling, it would outperform it. But you don't think so, eh?

Hmmm...

I cant say that I have ever seen or tested a Black Ice Pro III, but if it is aluminum and only has 3/8 fittings, The heater core will beat it. I am going by what other people say too.

I'll add my 2 cents in, as well.. I agree with everyone, the heatercore is better. from what I've heard, a dual heatercore (heatercore that can use 2x 120mm fans) will match beat a TRIPLE 120mm radiator. Ive got the '77 Bonneville in my system with 2 Thermaltake fans on it. With a venice at 2.6ghz, an x800xt pe at stock, Im getting idle temperatures of 29C and load temps around 35, give or take depending on room temperature.
