Now that is cool :-) EDIT: UK outdoor mining temps

I'm in the UK and keep my mining rig in the garage outside.

Temp    Fan% (rpm)    Load  Rate     Accept/Invalid   Status
0: 42c     na% (na)      99%   218 Mhs  538/0 (0.00%)    pool.bitclockers.com

The cards are:

0 5770
1 5830
2 5830

All over clocked as you can see and the fans at this time (8am UK time) are at 50%

So you are essentially setting up a space heater outside?  Why not use it to keep your house warm?

2 main reasons really, given its an open frame rig

1) Noise, though granted that can be "managed" to a degree
2) Kids, sedate, giveaway, bury at the top of the garden? dunno if I'd get away with that :-)

What kind of rpm does a 5830 see at 100% fan ? My ASUS 5850s run between 41 and 49% fan which equals 2400 to 3000 rpm.

I would have to check but given the figures above I'd say 2-2.4k rpm.

Card 1 is a sapphire which has proven to be a superb card! clocked to 1010mhz and stable as a rock.
Card 2 is a XFD pile of crap, clocks to 975mhz, runs hot and a crash means a system freeze.  Note as the environment becomes warmer the temp diff grows... during summer the XFD was about 12 deg C above the sapphire (bearing in mine the Saph is clocked higher).

I have noticed though as the figures above show, between the 2 brands of 5830 I have, 50% fan on each is a significantly different RPM, the difference grows as the percentage rises.

Well i was more thinking that it's perhaps 2k7 and 2k9 at 50% but the slower the better (less noise).
