a few of you have been wanting to see temp comparisons between the BIX (first gen) and a heatercore (1/2" fitting mod)

BOTH rads are 6 channel - double pass.

the chevette heater core FIN AREA measures 6 1/8" x 6 1/8" x 2"
the BIX FIN AREA measures 4.7"x4.7"x 1.25"

now the BIX fin area actually has water runnin the whole 1.25" thickness, the core has it running about 1.5" of the 2" thickness.


What i did for the bix was put a panoflow 120mm mounted to one side of the built-in shroud, the fan was run at very low speed.
The core was fitted with a 2-3" tall shroud, and the same fan at the same speed.

The cooling setup:
Rad > small resevoir > Eheim 1250
then it splits off to a MAZE2 and chipset cooler on one side, and a video cooler and hd cooler on the otherside
then both come back to the rad.

the CPU is a Duron 850 @ 1000 (1.85v)

now the part you wont like =) for the IDLE temps, i used vcool (a cpu idleing program)

the max temps were achieved with toast and prime95 running at the same time


all temps were recorded with MBM5 and are ALL off by exactly 3 degrees lower than my DD5 reports. but they are consistant and they provide good comparison. so here they are:

AMBIENT: 19C

BIX IDLE: 27C
BIX MAX: 40C

Core IDLE: 26C
Core MAX: 37C

now remember that these temps were from a LOW CFM fan.. well actually just low voltage but still, if these were HIGH cfm test im sure the gap between the rads would be much less.

now what does this test say? one rad has a higher cooling capacity, one is more efficient, maye one is better at lower cfm and one is better at high cfm(not that the test shows it)?
ill let you guys have at it =)

edit :
forgot to say its all 3/8" tubing (kinda defeats the purpose of 1/2 rad but hey...) and remember.. this isnt a review or benchmark. it is just MY results on MY setup. but the readings are accurate, and they are to give you something to look at being that nobody has really done any BIX reviews.
