A Few Temperature Questions (PSU

However, even at this temperature, atoms and molecules retain what is known as zero-point energy, the lowest possible energy a system can have. Seems like it's perfect for accurate fan and case airflow measurements, and realatively cheap. For the second experiment assume again two electrically identical PSUs (identical fan), one with large heatsinks and one with small heatsinks.

But it doesn't tell me how well that heat is handled by the PSU. Worth experimenting with this a bit; will see if differences between PSUs show up. I dont have any front bays open so the duct would have to go thru the top of the case and would be a pain. At my case PSU is located in dedicated chamber in Antec Mini P180.

AMD's idle temps are generally inaccurate. sorry Mike... So all positive voltage rails have +/-5% tolerance per ATX spec. –sawdust Nov 19 '12 at 3:14 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote You may also...

This state of matter is known as a Bose-Einstein Condensate (BEC). testing/measuring: -airflow from each fan. ( case fan/s won't vary significantly for a given voltage), and at intake. What you will be measuring is how much air the fan moves and not how much heat the PSU generates. It might sink a bit more into a metal case too, again very minor.

At sufficiently low temperatures, for instance, some types of matter become superconducting, carrying electric current with absolutely no resistance. And point well taken that the number you really want is the real world temp, so might as well just measure them. I am using the PSU as the only exhaust point for my latest project. http://www.techsupportforum.com/forums/f210/psu-and-temperature-questions-576309.html Top quokked Post subject: Posted: Wed Nov 06, 2002 5:59 pm Joined: Sun Aug 11, 2002 3:26 pmPosts: 333Location: Melbourne, Australia MikeC, this is a really good idea,

To Chan, these are examples of macroscopic quantum phenomena—quantum mechanics operating on a macroscopic scale.

With it, you can either turn up the fan manually or setup auto ramp up base on card temperature. Yes, it is definitely running hotter than it should, and it wouldn't be the first time I had seen an EVGA card start to run hot after a few years... The outage also disabled my sound card. At that point, once you know your voltages are where they should be, can you know if those skewed voltages were causing the card to operate incorrectly, and run hotter than

what it all tells us: -efficiency of PSU in a realistic setting. -performance of PSU in a realistic setting. -PSU's thermal contribution to a realistic system. -temperature performance of a realistic http://quodsoftware.com/a-few/a-few-questions-about-compatability-and-performance.html Ask a question and give support. Issue 3: Voltages This is what speedfan is saying for my voltages: Vcore1: 1.01V Vcore2: 1.90V +3.3V: 3.31V +5V: 4.95V +12V: 0.51V -12V: -16.80V -5V: -8.43V +5V 5.13V Vbat: 3.25V Vcore: Seems like something that is easier to misinterpret then interpret correctly.

I would agree this is a MUCH smaller effect then CFM but it does exist. Then any differences would be due to airflow impediments that you could rightfully fault the PSU for, and even suggest remedies for. The thermistor would be positioned at the center of the end of the tube. http://quodsoftware.com/a-few/a-few-questions-for-gpu-upgrade.html Gear in this thread Flycam Flowline 750N Professional S Flycam introduces - a Professional Ergonomically Stabilizing Camera Support which is an Ultimate Bod More on Flycam Flowline 750N Professional S Price:

The results of these experiments will lead you to conclude that the more thermally efficient PSU "runs hotter" then a less efficient PSU, which is of course the exact opposite of One thing I am thinking about implementing is to set up a standard heat source -- like a 60-100W light bulb -- in an empty case to simulate CPU and other Some even have a laser pointer.

And because i can't seem to diagnose my problem, i'll assume its the culprit, but i'm not sure so i'll just post my situation here and see if you guys can

I wonder if I can find an accurate temperature point at which I should be concerned? Take a close look at the temperature data provided in every PSU review we do. Not really... Chan's own research at very low temperatures yielded another important breakthrough in 2004. "My former student, Eunseong Kim, found that solid helium also exhibits superfluid-like properties below 0.2K," he explains. "Finding

But then there's so many thermal control reliant ones Testing in a real case would likewise be smart since sinking heat to the case is a potentially valid stategy, even a Intuition is a help (I mean own audio DIYing), but it is much more helpful to get infor from first - your - hands familiar with plenty of different PC hardware Maybe it would allow a quieter system than one with a quieter PSU + second fan. his comment is here Temp is only one factor though -- electronic components (that go into PCBs) rated for higher power can sustain higher temps that those rated for lower power...
