Being that it's ALREADY getting cold in a lot of places...
Let's assemble pics and screenies of some super COLD Aircooling OC'ing.
If you can... please include a pic of a thermometer showing ambient.
This is on Tforce, default vcore, TT BT. Nomally temp showing around 30 idle, 40 full load. Everything was placed near window just to test if I can get sub zero cpu temps on air :D It was like -20C outside. Max oc was +100-200Mhz but temps went up to around 10C idle because of higher vcore
http://xs308.xs.to/xs308/06421/coldair0.jpg
Last winter:
#1 - Prescott E0 3.0GHz
The rig (ambient temp -31C)
The result - 4510MHz aircooled Prescott (1.6V)
#2 - Northwood 2.66GHz
The rig (ambient about -26C)
The result - 3658MHz aircooled Northwood (stock volts - P4i65PE cannot change Vcore :()
3759MHz BIOS screenie
#3 - FX57
The OC was on the roof of my house (9 story building) it was like -31C with heavy wind. My camera wasn`t able to take the pics - it was all frozen :(
The result - FX57 @ 3.92GHz (DI) + some crazy TCCD clocks (3.5V)
lol we are moving into 35C ambients and you guys -25 hahaha
i guess i'll be back on the forum around June again :D for some 10-15C ambients
Cold is good for hardware (well except hdds) but not for humans :D I would rather have 35C ambient than -30 :p:
I already feel cold when the temperature drops below 10°C, let alone benching outside when it's freezing below -10°C :pQuote:

Pretty soon now.
will wait also for your result rev.. :woot:
Good thread Charlie :clap:
I'll be hopefully adding something to this little competition in the next 4 months or so.

This was 2 years ago, when i finally reached the 27s 1M and 3000MHz on my 3200+ Winchester! It was really some fun! :toast:
As far as i remember it was about -2°C.
it was winter outside -10°C.... inside the room -2°C

Was condensation an issue there rugg?? LoL though... :toast:
no condensation, the air was to cold :)
ruggero, you are definitely number one until now in that thread :toast:
Subscribed.
Darn i wish it was winter here :rolleyes:
Btw do heatpipes still work ok in the cold? Just thinking that the liquid inside would still vapourise at like 30C or so :confused:
ITs warmer out today, its almost reaching 70!! :(
Thats it im putting my side panel back on> :(
thats funny i was going to stick my Rad in my window this weekend and see how cold she got. lol.
i will get freeze out b4 pi 1m finish.. lamoQuote:

Thats an error. I get the same value when I try to use smartguardian with boards, it doesnt support.
He used it to display voltages I guess.
It is biostar Tforce not DFI, and it only supports cpu temperature and some voltages :)
lol... this is great.
Anyone who catches pneumonia benching outside gets special props.
:D
:woot:
That is actually closer to the truth than you think. This is my record from last year, 1.4C ambientQuote:

When you bench all night actually in low temps the cold really sinks into your bones.

You have to drink A LOT of rhum and make a bonnfire on your room/balcony/whatsoever. I hope(or not) we get some -30 celcius on next winter here in the southern finland so i could try some aircooling again or place the watercooling radiators on to the open window. C2D gets beating after that.Quote:

Nice job man :O
Awesome ! :D
wow... top!!!
Im currently using a 6" round high CFM blower with a flexible 90 degree elbow to pump cold air when its avalible through my main rad on the water system which works excellent and provides cold air for everything else in the system as well. I got in the Thermalright HR03 sink for my X1900XTX so this weekend its going on for testing, hopefully the temp here will drop down a little as its been in the low 70s the last few days. Once we get some colder weather I will throw some pics up.
:D According to Your SIG all the chips I killed in the past 5 years have been shouting out loud:Quote:

-20°C in October........... - where do You live, Northpole....
Hope for a few days with around -10 to -15°C here too! Then i will go outside with my rig immediately! :toast:
With my Opteron 146 it was no fun.. i tested it ones, close to the open window, with about -5°C outside, but this CPU had a really horrible coldbug.. +14°C @ 305MHz HT.. :stick: :p:
:confused: Yeah - on the Zugspitze or in the higher Alpes. I'm in Germany, too and weatherforecast says 19°C - but in the positives......:stick:Quote:

But romours say if we have such a mild October here there will be a lousy cold & dry Jan & Feb...., good ambient for outdoor experiments.

U interpreted it wrong.. ;)Quote:

:toast:
Youd just need for example zalman 7700 for your subzero experiments because the heatpipes doesnt work that well on those conditions.
:D No - watercooling mixed up with enough Vodka in the circuit.....:p:Quote:

:woot: Very nice Thread!
I have still two questions:
1. Do the Heat Pipes still work? Cpu Cooler and Mainboard?
2. Are there any problems with condensation? Also when you get in again?
Thanks Smash from Germany
1)heatpipes DO work :D
2)short bench-sessions usually got me no condensate :D
If you got condensate - use hairdryer :)
My geography class memory tells me one of the best places in the world for subzero AIR COOLING would be Novosibirsk, Russia. Brutally freekin cold about January.
:D Your SIG is wrong - has to be "Be cool and stay fool" .........:lol: :ROTF:Quote:

They dont work. i nearly burned my Sandy, when ambients was -20c. Temp was 60c+ with BigTyphoon, before i switched PC off.
With 0c ambients i could get 8c idle on CPU.
worked fine for me with ambients of about -10C
Ok, then it probably depends on the cooler.
Perhaps we can make a list with working and not working coolers for subzero use.
@TaPaKaH
Which cooler did you use?
I used TT BigTyphoon
Oh:confused: Perhaps there is a dead point.
So what say other subzero ocer?:D Post your experiences!
I just LOVE that design :woot:Quote:

Also i wouldnt be worried about killing cpu because eventually it will get hot enough to heat the hsf up again :p:
using this cooling helped - heatpipe did not freeze (temps about 0C)
Respect man!!! :toast:Quote:

So, i have just made up a hew thread in a German forum. Otterauge said that it perhaps depends on the Paste("Wärmeleitpaste" don't know the Einglish word right now:D )which you use.
For example, he once said that Coollaboratory Liquid Pro isn't good for subzero use.
@TaPaKaH and Kasparz
Which paste did you use?
I always use ASceramique :up:Quote:
Which paste did you use?
Subsero air hm i live in northern sweden not far from the artic circle , perhaps i should try some oc-ing when its -30 to -40 with watercooling :D
I vote for sticky, I will definately be trying to get some results when the temps start going down here again, it is not uncommon even here in PA to get temps into the -20c range
THIS would be a great subzero aircooler.
http://us.st11.yimg.com/us.st.yimg.c..._1920_84852926
Put the biggest monster 120mm on it with a 92>120 adapter.
Lets add another wrinkle.
How about some of our more XTREME members try running a high power TEC aircooled? Take the above HS/F, put a TEC under it and add a little copper coldplate under the TEC and above the CPU.
We've theorized for years that TEC's have a point where the cold doesn't help any more... would be nice to see.
man...this was nice :DQuote:

Yes, low temps are hard on HDD's so simply wrap one in insulation and it's own heat will keep it warm.
LCD's.... hmmm.... I'm not sure about that.
My HDD started to do strange things, with about -5°C ambient, so i think it is better to keep the HDD at ~ +15°C! :)
I really look forward for winter.
a run outside is scheduled for some more GPU clocks.
I use stock heatsink on it so without ambient sub, no good clocks for benchies with my X800GTO :(
Plain aircooling is really the best for subzero i think, because water is responding to slow with the ambients. Think i will install my XP120 with my 120x120x38mm Sunon then! :toast:
If the heatsinks based on heatpipes do not work anymore, then I think the good old copper heatsinks (those from thermalright back in the Atlon XP days) might give you the best performance. There are a few other non-heatpipe heatsinks out there, like the one from Swiftech above, or those from Alpha Pal. Don't know about newer heatsinks, those days it's all about heatpipes.
Basicly there are no heatsinks out there that can handle high end TEC's with overclocked CPU. And the temp difference on chipset's or other stuff would not be big enough to see a real differance on your overclock. Besides that, we do love watching graphs, so if someone feels like doing stuff like that, please do so ;)Quote:

oh and BTW, any OC'er who catches pneumonia while benching gets extra props.
:D
I'm running the stock AMD heatsink on my 3800+ orleans which is just an aluminum brick so that should work fine sub zero, the stock 7900gt heatsink would too but i was hoping to get a vf900 - hmmm

Perhaps can everybody post which paste was used. So we can get a better result.
Artic ceramique would be best for subzero temps.
yes absolutely... AS Ceramique is EXCELLENT. Also, the standard low budget TIM that comes free with hardware (the plain white stuff) is good, too.Quote:

dropping back into the 40's here(close to 0c), if we are lucky i may bench again this weekend...
on the other hand i have a maximizer coming my way i may just wait until then
Fargo, North Dakota
My research show a trip there about January 15-25 would yield easy -10F temps(-23C)
This might be fun... Los Angeles to Minneapolis is about $230 and that gets you within 200 miles of Fargo. Then AMTRAK will get you to Fargo in 4 hours for $36.
Now I need to find a hotel with a balcony/patio so I can put rig outside with KBM inside.
My weapon of choice:
Asus P5B Deluxe. I will probably cover the caps with spray insulation. E6700 should do fine...
Need to bring a couple HS/F's... I'll try a Scythe Infinity to see if HP work. And I'll bring a Swiftech HS and a VT Tornado.
Hmmmmmm...
:woot: What an adventure. The Infinity is good, but do you not think a P5H DH would be better for a Conroe?
Since I'd be OCing for max gHz I'd want to eliminate any possible FSB walls...Quote:

The tears in my eyes had turned to ice. If you want to get extreme go there it will be ridiculously cold in January.
Man, I wish I lived somewhere that it got down to -20C, I'm lucky if it even gets to 0C at night, during the winter.
This past week has dropped temps down drastically and fast.
This week Im finishing up my benching here inside then this weekend I will take it out to the garage.
Im hoping to get my 165 around 3ghz.
I did this last year and got my 150 to 2.9ghz.
Its great fun running back in to the house fast enough to keep your hands from going numb :D
