ii have been trying to find 2200UF 16V caps and all i am finding is 2000hr @ 105 -55-105 is that an accepable operating life time?

Re: Question about operating temp and life span
That 2000 hour rating is Endurance, not Life Time. It simply states for how long you can "abuse" the cap with maximum ripple, voltage, and at max temperature (105C in this case) before it goes out of spec or vents.
Rubycon PX is general purpose series. Usually not good enough for PSUs and definitely not good enough for motherboard use.
As far as 16V 2200uF caps in a 10 mm diameter can - yeah, those are hard to find indeed, especially PSU grade. For PSUs, AFAIK Samxon RS is pretty much the only caps you can find in that capacitance and size.... unless UCC makes some custom order caps for us (see this thread).Last edited by momaka; 03-11-2013, 07:22 PM.Comment

Re: Question about operating temp and life span
That thread is for 16V 3300uF caps...As far as 16V 2200uF caps in a 10 mm diameter can - yeah, those are hard to find indeed, especially PSU grade.

16V 2200uF caps in 10mm are available:

These are suitable for power supplies and have a 4000 hour endurance rating. I wonder what those endurance ratings actually mean.Comment

Here's an unusual one...
This is a Gallenkamp oven, used in a laboratory space, goes up to 220 Celcius, but is usually maintained at about 115 Celcius. Used for drying glassware, molecular sieves, and so on. Oven is in excess of 20 years old.
It heats up fine, there is an orange light on the front that indicates that the unit is heating, and when it reaches the preset temp, the orange light goes out. All good so far.
However, after the preset temp is reached, the temperature continues to rise, power to the heating elements isn't cut off.

Hi to all, my motherboard (bought second hand as faulty, but now working after cleaning the ram slots) have a strange failure that shows 0 Celsius degrees in BIOS, because of that, the CPU goes to protection mode and gets stuck at 800Mhz.
Since its a 8-9 Intel generation, I know the CPU temp is the hottest temp of the cores (as i have read in intels documentation) so its not a diode or sensor on the board.
External temperature (motherboard temp) is working OK, 27ºC more or less
In windows, all the software I have tested shows correct the Core temps

Is 98C vram temp are safe? Less demanding games goes 80ish.
Funny thing, there were old non stock thermal pads very botched, so i replaced them. After, temperatures remained the same, but performance (fps) improved significantly. With both thermal pad application GPU core temp was similar.
furmark goes about 104C, amperage keeps rising so do temps. -
Hi.
I have a laptop Dell Vostro 3501 which did not POST. When connected to power supply and turn it on, the keyboard backlight would turn on but nothing else. Sometimes there was 1 BEEP code indicating problems with BIOS.
Then I disassembled it to read the BIOS chips. It had 2 - 64mbit and 128mbit. I connected CH341A (with 3.3v mod) to both of the chips (still soldered on main board) and read them.
After I reassembled laptop back and tried to turn it on. Now there is no sign of life. Not even keyboard backlight.
Then I took the motherboard out... -
Hello,
I'm reading an article about the "capacitor plaque" in early 2000s and I have found one sentence I cannot understand.
The normal lifespan of a non-solid electrolytic capacitor of consumer quality, typically rated at 2000 h/85 °C and operating at 40 °C, is roughly 6 years. It can be more than 10 years for a 1000 h/105 °C capacitor operating at 40 °C.
What this 2000h or 1000h means? Why 1000h capacitors have longer life span?
