Finally got some cold weather...

...here in Houston, so I opened up the window, juiced the voltage a little, and bumped the FSB up to 148 Mhz. 🙂

Amazing how the ambient air temps affect the PC. When the heater is running and it gets warm upstairs, CPU temps will go to 48-49 C, with cool outside air just a few feet away, temps drop to 35 C. Though the ambient temp obviously matters, it makes me wonder if I don't need to do some ventilation work on the box. It's a SuperMicro mid tower, I replaced the 80 MM intake with a 120 running @ 7.0 volts (quiter, but lots of air) on a frame angled slightly up at the CPU area. The case does not have a rear exhaust option, so the PS fan is the only way out. May need to think about a blow hole perhaps to help move air out of the case?
 
It is fifty degrees Fahrenheit (-46 C) below zero at my house right now. I have a Multiplier Unlocked 1.4 Ghz Athlon ThunderBird. If I stick it out on the porch, how much do you figure I can overclock that baby? 😉
 
At 148FSB, what's that baby running at (mhz)? 😀

Did you have the case on or off with the cold air coming in?

If it was on, then it sounds like the fan is doing a good job of sucking in air and cooling the CPU, unless you were expecting a much larger drop. What is the ambient temp of the room with the cold air in it?

Ah heck, who cares. Just go open a blow hole in the thing for the fun of it. 😀
😉😉😉

Of course we will want PICS!

🙂🙂
 
Case on, 1628 Mhz (it's a XP 1700, 1.47 Ghz).

According to the thermostat downstairs the temperature got down to 62 F in the house, my wife just threw a fit when she got out of bed and I had to turn the furnace on 🙁. Perhaps I should have offered some alternative warming options??? 😉

MBM is now reporting 41 C for the CPU and 25C for the system temp. So I guess the ventialtion is decent as there's a 16 degree delta. The real challenge will be figuring out how to cut a blowhole without shutting down the PC so I don't lose any crunching time. 😉
 
Steve, just be careful it doesn't get sunlight on it 😉 (I know that's not a problem where you are at this time of the year)
It would definitely make an interesting experiment. Have you seen the experiments done with putting components in a freezer? They used junk so they wouldn't lose valuable equipment but they could get a 10X normal speed OC.
Of course also there's the guys who cool the cpu with liquid nitrogen. Brave Souls. They got a P4 up at about 3.5 Ghz I believe.

Things to be careful of when freezing your computer:

Condensation caused by contact of cold air on components that generate heat. This is a killer, as water droplets will short out and otherwise corrode your parts.

From my memory of the times I have visited your fair city in January & February that's a pretty "dry cold" you have. I would still want to take a measurement of the relative humidity in the room where the pc will run. At that temp it's doubtful there will be any humidity, but what happens when you open the door of your heated and humidifie home to the non heated porch?

It may run fine as long as it's cold out there and it's just left to run, I would be careful with the cool down phase and eventually the warm up phase (when the sun comes up a bit higher in your sky. I would block off or otherwise protect the case from getting sunlight on it when and if it does eventually come around.

If you do it I expect to hear what happens here.

We actually got a little snow here in Snoqualmie this morning!!
 
Gawd, I'd love to have access to -50 air! I'm thinking......

1. Sabre saw, cut hole in side of house, install small vent cover over hole.

2. Throw some of those little silica bags in 4" flexible dryer duct (to "dehumidify")

3. Install 120 MM high flow intake fan.

4. Duck tape the 4" hose to the intake on the PC and connect to hole in the house.

5. Run Norton Ghost, back up HD.

6. Turn voltage and everything else up to the max.

7. Reinstall after I courrupt HD data.



:disgust:
 
man jim dont laugh........i have read ....on this site.....where people have done exactly that.......bored holes through walls or floors and got cold outside air for there cpu-case ventalation

thats dedication......lol................

go for it....😀
