G H Z, it hurts as a norwegian with no snow this year to see that lovely pic! ;(
Anyone had condensation problems running their systems outside?
I'm planning on running my prescott in the garage (separate from the house, not heated so temps about as low as outside, minus the wind) or something, but I dont wanna break any HW so I was wondering if there could be any problems?
//edit: damn I should have done it today! -22c -31c incl. wind
-8c here in pa, says windchill is -15c lol. Gotta spend today relearning my board then tonite she goe's out the door on a cart =)
-10c was to cold for the olde big typhoon. 4.14ghz on my e6600@1.64v and the heatpipes froze up after 45minites or so. After a reboot to go for another shot at 4.14 3dmark01 stable she wouldnt boot anymore, reset to my 24/7 settings and was idle'n at 58c, dont want to know what temp was being generated at 4.1+ 1.64vcore when the heat pipes quite working:eek:
I forgot to shoot a screen with smart guardian up unfortunatly.

Dont say i didn't warn you.Quote:

it would have been fine if i hadnt been learning a overclock, i was out there a while. 30minites at a time would be doable.
Really great air subzero. Geographical advantage? :)

Some test with my Opty 170 0610dpmw got some problem with it...to get higher but i will try to fix them.
1. Using Big typhoon and with to much cold the temp geting higher...(becuse of the gas)
2. The chip have bad coldbug like my 0617fpmw...over 350htt and core temp around 0c...i have not got into it yet on this chip but i know its are close...so i can improve the clocks abit(i need to hcange the coler first)
To bad my 0617fpmw was a 165... it about 30-40mhz beter than this chip...but the cold bug is in the way with only 9x multi

What exactly do u mean with "The heatpipes froze?" and stop working? :woot: Cant the big typhoon handle -10 c?Quote:

Ima go benching in one of the days lol ;d
Look a our weather.
-10
:stick:

ah i get it now, I didn't read what Lastviking said about the gas, and of cource that is the answare. My bad! ;)Quote:

I'll see ya on the other side
I don't understand why a heatpipe would stop working in cold ambient. If it started to function poorly then surely the cpu would heat up and this would heat up the base and this would make the heatpipe warmer so it started working again ? :confused:
First coldish night tonight. Ambient is 2C at the moment in the shed, in the BIOS at 1.30v and stock 11x266 2.93Ghz X6800 the cpu temp is 7C. I'll get up early tomorrow and take a picture plus a run through 8M SuperPi to show what fully loaded temps are.

I was unaware that a phase change happened in a heatpipe cooler. :confused:Quote:

Finally some moderately cold weather in UK, shed ambient was 0.5C at 4.45am when I left for work.
Stock voltages and Mhz for this X6800

Bios reads at least 10C low.

Half way through a Superpi 8M run. Tuniq Tower holding up well.

Where I live right now, a military camp far north in Norway it was -30C at Wensday. To bad I don't have a computer up here. At the coldest point in the winter it can get as cold as -40C. Brrr ... And at that tempereature I've to run arround in the woods and play war.
In Bulgaria its still warm...about +5/+10Celsius...As the news say the temperature will fell this days :) It should be about -10/-15.I hope so.And i will try to make my 7years old Intel Celeron (Codename: Tualatin 1200Mhz Default) which now works at 1600mhz 24/7 to run at 2000mhz.I cant set more fsb than 166 with open jumpers....:(

Nice work.

1.2°C was the water-temp... ambient was -2°C ;)
