I've seen too many ppl. bitch that the iceprobe is junk .

The gearhead inside my brain has been visualizing a old schhol brass heater core from an older model car , w/ a 115v dc. muffin fan secured to it using the hold downs that would come w/ the trans coolers you've been looking at , pump driven using a powerhead pump from a fishtank . I'm making one next summer in hopes of not having to do dirt anymore in the hotter weather .

Whatcha think ? A heater core has a larger capicity , and more rows / cores to pass thru = better chance / longer time to tryn lower temps. than a single core transcooler .

Check out Coolerguys.com offers cool PC solutions for the computer enthusiasts. CPU Coolers, Quiet Fans, Cables, Lian Li, Koolance, Computer Cases for 115v ac muffin fans w/ cords and lotsa balls . They have 1 that moves 105 cfm for $19.00 w/ the cord .

If all else fails search "Shaggytodope" he has a thread w/ monster trees here , there's a link in that thread w/ killer prices on an res/aquarium chillers .

Peace
