Also, that could be a good idea when using it on your lap, so as to avoid <a href="http://channels.lockergnome.com/hardware/archives/20050208_overheated_chips_get_doused_by_readers_suggestions_for_cooling_systems.phtml">lap-burn</a>. :-)

Hi Naylor

I like that!

Today I read the following advice about cultivating orchids. Place a large bowl of water on top of your desktop computer. Suspend (yes, suspend) the orchid above the bowl so that the rising water vapour creates a rainforest environment.

Do you think this counts as water-cooling?

__________________________________________________

I think we'd need UK_Nick's opinion on that one, Mo. :)

Mine is: That'll do the computer a LOT of good!
Especially when children/pets/visitors knock over the bowl.

But it does show that people are aware of the heating possibilities of computers.
Perhaps people with 'farms' of computers could operate them in their greenhouse / hothouse / etc.

A good check is:
Check temp with computer idle for 20 minutes,
then check it after 20 minutes of full load.
If I remember correctly, then it should not be more than 10C difference, there-abouts.
I have not done this for a while, but will post if I get to it.
Edit:
The above check takes into account software misreading the temp.

Mo and I are joking. HA Ha Ha.
Perhaps in Canada humor is different?

My post was for Naylor about temp. checking.

As for the Orchid post, yes, obviously a joke Yet, increased humidity will give you better cooling/heating.
Also, if you have a hard time keeping home warm in winter, heat always coming on, check humidity levels, they may be a bit low. It is the air we say is warm, but it is the water it carries that gets and holds the warmth.
More water, longer to warm, longer it keeps the warmth. That is why rocks are/were used in bed-warmers when central heating is/was not available, long time to heat up, long time to cool down.

Very interesting, since I sometimes think my bed-warmer has rocks in her head, but I've never had the guts the tell her, directly. As for the "long time to heat up" situation, I've found that some spontaneity, creativity, &amp; ingenuity, can substantially shorten the warm -up time, but this can vary greatly on your bed-warmer's mood. But, creative persistance usually works.

I agree with your last point completely. In issues resulting in an argument, or even events perceived as a transgression on my part, whether accurately percieved, or not, my bed-warmer can take an unbelievably inordinate period of time to cool down; Sometimes lasting for days. During periods such as this, my bed-warmer's heat-up period may be extremely long &amp; difficult, or even non-existant, with all my efforts ending temporarily in futility.

I'm in my mid 40's, and after having over 25 years experience with bed-warmers, I still find I've only come to understand, at most, maybe 70%, of how they operate. My current bed-warmer, and I, have been in an exclusive one-to-one mutual ownership situation, for almost 6 years now, and I still do not completely understand how she works.

Bed-warmers are an absolutely endlessly fascinating subject of study, for me, and I've devoted much of my adult life to this pursuit. I'm sure I'll never have a full grasp of how they function, but they enrich my life immeasurably, so I am more-than-willing to live with what I perceive as "an occasional idiosyncrasy", which I'll never understand, nor comprehend.

Is that a bed-mate induced edit I smell coming on? lol

I hope you have the relationship that if she saw it, it would be no biggy, just another point in life that could easily be turned into no need for rocks that night. ;) ;)

'course, you might need to strap maracas to her butt to get that familiar rattle you're used to! haha

Touche' ;-)

Yeah, bed-warmers can seem pretty innocent &amp; innocuous, but they sure have a lot of subtle weapons at thier disposal when angered, not the least of which, you described in your second sentence. 'Course, I'm speaking of the "Venus" versions of the bed-warmer, which is my preference. Women usually seem to prefer the "Mars" versions, and ironically, also cliam to often have a misundrstanding of how thier bed-warmer works.

Though, I believe it's possible they may understand more than they let on.

&gt; is?
&gt;
&gt; I just occasionally feel the temp of the air coming out of the back with my
&gt; hand. I clean inside and out from time to time with a mini paint brush and
&gt; vacuum cleaner.
&gt;
&gt;
&gt;
Try SpeedFan, it's what I use.

Or MotherBoardMonitor, MBM, last version I got was MBM5370.exe
It will monitor fans speeds, temps, etc. etc. with various options for display and alarms and the ability to adjust how often it polls for the data. On my "warmer" machines I run it from startup as a systray icon and let it keep logs.

Hi All

I have still not understood how a programme you install on the computer can measure (or deduce?) a physical condition like the temperature in part of the box.

How on earth does it do this?

---

__________________________________________________

Hi mo.v,

there is a thermometer on CPU - actually it's insede. I remember having a external termometer on Pentium II, back then. There is also one that measure mainboard chipset (which may tend to get hot as well) and some modern VGA has this feature on their GPU (graphic processor). "Modern" VGA cards can take 50Watts and also get very hot (60+ C).

The problem is that it may not be as accurate as i seems and not every chipset solution is supported by every application (e.g. Speedfan, MBM and others).
So, one may need to checked several appication before he sses any numbers.
Quality mainbaords has a CD with such applications...

Thanks, Honza, that explains things.

As there is a thermometer there, would it be possible to invent a temp display on the outside of the box, or on the screen, rather like a car's temp is displayed on the instrument panel?

Some cases do have temp readings on the front.

You can simply test the behavior of the system as it changes do to heating. Most CPUs today have this built in so that if the heatsink is off and the cpu started it will not melt ...

Add that to the chips installed on the mother board, or simply add a standard thermal sensor ... and now you can see temperature across the MB.
