Thanks Chase!
Honestly, probably a good temporary fan but I think I'd rather try to find
the OEM M33402 or something at least a tad bit stronger while not exceeding
the 140mA rating of the Nidec. I'd probably go with the E34386 which there
are plenty of on Ebay. It's a little weaker at the same pressure drop
through and i'm not super thrilled about the sleeve bearings. Sun
lunchboxes are already pretty poorly cooled and I hesitate to go for
something possibly a little weaker. The 14cfm is measured at a particular
pressure drop and without seeing the fan curve of the Amazon one I don't
really know how it would perform at that of the Nidec's DP. I found another
lead but waiting on confirmation if it's in fact the M33402.
