So I was playing fallout 3 smoothly and all the sudden i get 0.5 fps for about 20 seconds.. happens randomly afaik. So I open up HWiNFO sensors because I was just looking randomly for guilty things and I come across this, Is it normal? mainly the +3.3v. Forgive my complete ignorance regarding PSUs.

Well White not all of those programs are 100% accurate, they give you a guesstimate but not accurate reading.


A reading of 2.176 is not unusual with software related voltage reading programs.

The most accurate way to determine if those are accurate would be using a VOM meter, preferably a digital LCD read out type.

You would put the meter in the Amps reading, then put it parallel with the orange wire which is 3.3 volts positive (+)

Yellow is +12 Volts and red is +5 volts, black is ground, blue is -12 volts and white is -5 volts.

You could also set the meter to DC volts range in the 0-24 volt setting, touch the red probe to the orange wire on the plug end and the black probe to the black wire and see what you get for a reading on the meter.
This would be a lot more accurate of an reading then depending on a software read out.

I hope Temperature 3 is a false reading. :)

I believe you are correct tg1911.

If they replaced HWinfo32 with the speed fan program, those senors would probably give out a totally different reading or none at all.

Each motherboard has various senors installed in them, the program you use has to be geared up with properly working with those sensors.

In other words, if the program is poorly written in lets say C++ or Visual Basic scripting language, it can either present a reading to a sensor that does not exist, or exhibit an inaccurate reading on one that does.

A good program should display N/A or something along those lines indicating a sensor does not exist anywhere in the system.
However some poorly written programs offer a false read out instead. This reading can display an alarming output, one that is telling the user of the program they have a sensor that is displaying a temperature of 1000 degrees Fahrenheit. :blink:

If anything, get a second opinion, try using a different program and compare the out put readings.

Now back to the concerns of White, below are two other programs we often recommend here at BC, try those and compare the sensor out put readings.

Well than.. I'm not too sure what I'm looking at but it doesn't seem too similar.. I would take bruces advice but I have this odd thing where I break everything the first time trying, and I wouldn't wanna break this compy. I just wanna know if its safe to keep on. well.. it hasn't blown up yet, besides from that incident a few months back where the metal case shocked anyone who touched it with about half the force of one of those prank gumpacks, than the USB mouse suddenly turned into an 'unrecognizable USB device'

Ahh, thank you for recommending speedfan MrBruce. I wondered why there was a picture of a flame next to the GPU temp and took a look in the case. needless to say I'm going to be coughing up dustballs for the next week.. yeah, about 3 solid mm of dust in the GPUs fan heatsink
Lock topic please ^-^
