Effects of Ambient Temperature on Temps

[a c i d.f l y]

Ambient temperature raised about 3°C, a noticeable difference between dehumidified airconditioning, and nice 100%humidity Texas afternoon heat...

...anyways, this was shown in a direct representation of my case and cpu temps. Case temp rose with exact coordination to the ambient temp (30°C to 33°C, case temps are kinna high?), and cpu raised from 36~37°C to float around 39-41°C.

I needa add another case fan, drop my case temps to closer to ambient... I figured I had good circulation given that temps rise when my cover is off? But I guess I was wrong?

Ambient is ~27°C. (80-82°F, up from around 77°F)

...point is, I didn't realize how big of an effect this made. A couple degrees, I need to watch this when the AC is off during the day, and the sun is blaring, and the house temps get around 30°C themselves, and see how that reflects in my case temps...

I know two years ago when the 1500+ came out.

My Dragon Orb 3 was fine until they broke the damned heat/air in our dorm.

Went from like below 72 one day and really good temps to 80-85 in the day and completely unstable even underclocked and undervolted.

The obvious problem of high ambient temps is that it raises everything else in succession.

I only remember it happining on the bad days, but one friends Dell PIV 1.7g would throttal itself now and again depending on if were were lanning or not.

On another note, a good friends A/C broke earlier this month and the 1700+ athlon system I built him with an SLK-800 was heat locking like a mofo.

I have no idea on humidity and it's effects on how moving air carries heat awat from radiators and heatsinks, but someone that knows the math behind it really oughta chime in on this post. It'd be intresting for all to know.

I halfway solved my problem by doing the same thing I did with this very PII...

Pull the case off and throw an 18" oscillatting fan blowing into it... Sadly enough it'd still heatlock some. Even after swapping to an 80mm sunon.

Humidity thickens air a great deal. And I don't mean 'compressed' as air gets when it gets cold. It makes air thick, and harder to move. However, I just simply mentioned humidity as an added thought to picture how easily it is to feel the actual room temperature difference in this house. The nasty wetness of the air - makes it harder to breath (not like life-threatening or anything, heh) - just a general sense that it is warm, wet air. Makes for a nasty, wet, sticky feeling. A person from Canada I don't think would have any idea what I'm talking about... a person from Louisianna.. I feel for you. :)

****, someone needs to come out with a user-based superchiller than isn't umpteen hundreds of dollars. That way we wont have to worry too much... just about the longeavity of our coolant.

*edit: PS: ..now that AC if in full effect, and it is night time, case temp is 29°C and CPU temp is 35°C. Too bad its getting into the 90's (fahrenheit) the last few days. Ambient is running about 75-76°F.

Oh man, Agreed. Every yankee I've ever met that came down here for the summer absilutly dies late June-mid september.

The worst part is if you don't get out and stay out in it, you kill yourself because you never get use to the heat!

Dry hot air is one thing, but warm air and humidity are the real killers.

The heat index without factoring asphalt at
90F with 80% humidity puts the heat index at 113F.

It's not the hot that'll give you the heat stroke that kills you. It's the fact that you sweat, yet it dosen't evaporate and you only become hotter. :\

I'd take July-August-September in Alabama over winter up north any day tho, ouch!

YUp, FL is the same way. I have to run my 2100 Pally at 1860 right now but was running fine over the winter at 1950.

Ohh it gets hot and humid here too sometimes, just not as much. Right now it's 98 in the shade and about the same humidity. my comp is runnong 49c with a case temp of 37 right now, that's with my new Maze 4. that's with just typing this post, any sandra or anything and it imediately jumps to 52-53.
