Anomaly: less diff = better. This is waterblock temp minus ambient temp.
Note that all test were run with a Eheim 1048 and 3/8" tubing.
The airplex and heattransformer dual are close enough, but the reviewer prefers the heattransformer because of its good mounting solution.
bb2k: he says good info, the results are interesting - thank you for telling this.
Yes its HUGE... Thats its only downside.
Sanjuro: the results are very close. I think the heattransformer wins because of its overkill size.
One thing worthy noting, is the best 1xfan rad - BIX tied with heattransformer single.
The difference is price. The HT is less than half the price of the BIX !
I'm already ordering one
