oooooooo overclocking fun!!

lookin good there helmie, oh and BTW, if you put the URL to an image inside
tag then they get displayed in the posts properly.
 
I dont know what it is with you ant not believing that i can get my cpu temp down to 6C. Its -1C outside right now, and according to my BIOS and Speedfan, my CPU has a temp of around 5-10C idle. Along with my video card dropping from an idle temp of 38C before the new cooling, to a idle temp of 26C.
 
Geoff, you gota give us all a guide on how do do that mod, those are some great temps. Preator, remember that with air cooling you cant go cooler than the air temperature, so if its -1C outside his house and he has a direct feed of that freezing air, then surely it can be done?

Hope the mods dont mind me posting this, but here i go:

I bought a dryer vent for $7 at a hardware store, i have one side facing down out the window (so rain and snow doesnt come in), the other side is glued to the back of my case, right over the 80mm fan (it covers pretty much all the air holes). Then i disconected the other intake and outake fans so warmer air doesnt come in, and the cold air doesnt escape quickly. I use the PSU fan for outake, but the fan speed on that is at the slowest. And i have a pci slot blower on the bottom of the case aimed at the gpu.

Here are some pics of the setup:

That picture above was taking before i glued it to the case, so right now its glued in place and theres tape blocking the other holes so no warmer air can get in.

Right now, its around 0C outside, and my cpu is ~9C, and my GPU is ~27C. Before i made this customized cooling system, my cpu idled ~20C, and my gpu idled ~38C.

Damn, thats a sweet mod. Theres some sort thing you can put through a thin wall or door, which connects to the hose. It would save having the window open all the time.

All the same, that looks great!

EDIT: Heres the sorta thing i mean:

ya i know what you mean, we have something like that for our dryer, but i just wanted to test it out to see if it would work. I think my parents would be a little upset if i drilled a big hole in my wall :P

My room is -6C right now and at night -12C easily (crommy am i estimating night temps right?). Now unless you're ducting directly or have the computer running out of the chasis (as i do) then you're not getting those temps. Furthermore, that does not consitute as stock cooling. Period. :)

Right now, its around 0C outside, and my cpu is ~9C, and my GPU is ~27C. Before i made this customized cooling system, my cpu idled ~20C, and my gpu idled ~38C.

See http://www.computerforum.com/showpost.php?p=239029&postcount=18 about the "post-modified-cooling" as for "normal stock cooling idle temp of 20C", that's crap and you know it. :)
 
Sounds about right for most nights, with the obvious exceptions of those freakishly warm ones recently.

As for the duct mod, wouldn't a 120mm fan be a better fit than the 80mm?

That won't prove anytthing, its to easy to photoshop.


Btw:you were also claiming 4C temps..

I did not photoshop the temps, they are exactly as they appear in BIOS and windows. These were taking when the computer was on for about 10 minutes, but once its been on for a half hour or more the temps get to around 6C (because it gives the case time to get cold from the below freezing air).

Well i believed you anyway . . . lol, but it doesn't matter what you do they will say it was photoshopped, or give so excuse, but i would like to say congrats on a nice mod and nice temps whether your telling the truth or not.

Thanks, i know some people *coughpraetorcough* dont believe me, and they may give me some technical reason on why it cant be that low, but the fact is that it runs that cold, mainly because its sucking in -5C air, and all the other fans are blocked so the cold air doesnt mix with warm air as easily.

Well i remember one time i got drunk with my friends in the dead of winter and tried to see how low we could get my comp to go and i opened the window and just set my comp close to the window and it got down to like 18 and thats without the duct or without trying to keep the air in.

HAHAHA, oh come on. I've been getting drunk since i was 16.

yah........sarcasm. hence the ;)wink;). lol.

but i know what ya mean;) check out my avatar.

BTW geoff. doesnt your room get cold with the window up and just the towel there or whatever to stop cold air from coming in? lol

1. You're a fool if by now you think that's why I challenge. You've made a misleading statement, intentionally so at that. To suggest that you're getting those temps with stock fan is a quick one way ticket to stupidity -- and no I'm not concerned about your stupidity (remember the "what's your FSB" thread?), I'm much more concerned about the casual reader who comes here and thinks that it's possible to get those temps running, as you so aptly put ... "stock cooling". In case im being too subtle (since in other threads, giant red letters dont seem to get through), "my main concern has nothing to do with the temperatures claimed but rather that you claim them to be with stock cooling which it most definitively is not"
2. Secondly, claims that you ran 18C idle on stock cooling prior to this modification are silly for the blatent counterexamples as noted above (it is however possible, say, if you room temp was -6C and you had a Manchester 4200 running at, say 1GHz with 150cfm intake .. but naturally this wasnt specified).
3. -5C isnt all that cold for intake temp.

To his credit, ducting outdoor temps directly to the machine will allow for the temps as noted (which is what I do as well, keep the room at -10C where environmentally possible)

  • Read the posts. He's not saying you can't get those temps, it's just not stock cooling by any means. From a thermo standpoint the dead state temperature is the lowest temp that is imediately available without additional work. Pumping in air from outside or from a freezer for that matter constitutes additional work and hence is not stock cooling
  • Though those temps may be correct, but I wouldn't count on it (though they are probably at least close) . Having dealt with many temperature sensors; even the RTDs that cost several hundred dollars are only accurate within a few *C. Basically they are meant to operate, and are accurate in, a specified operating range. Most processor manufacturers don't intend the CPUs to be at sub-zero temperatures.
