I can run Pi8m, 4.5 ghz @ 1.49v but computer will freeze on anything higher, and takes 1.66v to be orthos stable at that speed which is way to much for 24/7.
Ah, I see. Thanks for clarifying.
I've been doing some research on HSF/TEC hybrids such as the Amanda and the Vigor Monsoon II, and a few things have become apparent:
1). Both require more case airflow than your standard "quality air" solution
2). Not everyone seems to be able to get these things to outperform the TT Big Typhoon, and I haven't even seen anyone square either the Amanda or Monsoon II off against the Tuniq Tower 120, the TT Ultra-120 w/good fan (100+ cfm), etc. At least marky seems to indicate that in his rig, the Amanda does better than his Noctua unit, though he has not indicated whether or not he was using the stock fan or not.
3). In the case of the Monsoon II, a high-cfm fan like the Vantec Tornado was necessary to really make it work well (and attaching a non-stock fan like that required cutting some wires . . . bleh). Not sure if this is an issue with the Amanda and its two fans, though its performance might be better with faster, noisier fans. Whether or not it supports attachment of non-stock fans is unknown to me.
4). The Amanda is not currently available for sale in the US, and may never be.
So whether or not marky's results are legit or reasonably replicable is anybody's guess. Reviews on the Amanda (and the Monsoon II) seem to be all over the map. At $150, the Monsoon II hardly seems to be "worth it", especially since the best performance I've seen on it in a review required modding and the installation of a Vantec Tornado. The Amanda, on the other hand, *might* be worth the $100 if it can deliver stock performance similar to the Monsoon II + Vantec Tornado and if it could actually be purchased in the US. Heck, I might even look at it if it supported addition of non-stock cooling to bring its performance up to par.
for reference, this is the review where I saw the Monsoon II at its best:

It did very very well, but considering the fact that the total cost of unit + fan would probably top $160 after shipping and would require modding it to accept an aftermarket fan that is very noisy makes me question whether or not you could do as well with something like an Ultra-120, Noctua nh-12, or what have you and a 220 cfm Delta fan.
