Damn it, my struggle with shutdowns continues.
First of all: CPU temperature has been fixed with water cooling. It doesn't get over 60 degrees even playing. It only reaches shutdown-causing temperatures when doing high demanding tasks like video encoding. In theese situations i run BES cpu limiter so that the questioned program will use less cpu even though it takes more time to complete its work.
Second: my case is an homemade tower case made of steel so there may be some air circulation troubles. It has 5 fans on bottom, small openings on the back in the opposite side of motherboard and bigger on the side of motherboard. CPU has water cooling. Since motherboard's dissipator used to be hot as hell i added an inner fan pointig towards it to make air there move better (without that fan air was kinda stuck there, which isn't that much good).
Now let's go to the point: the shutdowns.
Problems identifyed: the mentioned CPU temp, which is fixed or in any case under control.
When it occured in non CPU high temperature (or not that i noticed)
- Playing WarThunder with high settings while recording with Open Broadcast Software.
I'm not sure about cpu temp when the shudown occured, i only know that after 40-50 minutes of recording while playing cpu temp was 53 degrees, nothing to worry about. The shutdown occured after almost 90 minutes. Just waited a little and the computer restarted with no problems.
Hardware situation right when the shutdown occurred:
Touching motherboard's dissipator i felt it was hot as hell. More hell than usual. Around in internet they say it's pretty well made, but i've some doubts since it really was... hot.
But also graphics card was pretty hot, i've never felt it as hot as today.
What i'd ask:
0) Do you think motherboard-graphics card temperature can be the cause?
1) Sould i extend water cooling to motherboard and/or graphics card?
2) Would extending water cooling to other components negatively affect its performance on the cpu? If yes, how much?
3) In case i need to extend water cooling to motherboard there's quite a big problem: the mofset for my model is everywhere out of stock (http://www.frozencpu.com/products/17962/ex-blc-1390/EK_ASUS_Crosshair_V_Formula-Z_Full_Board_Cooling_Block_Kit_-_Acetal_Nickel_CSQ_EK-FB_ASUS_C5F-Z_-_AcetalNickel.html)
4) Would having an additional graphics card reduce the amount of work done by a single card and then reduce card's own heat?
- Watching a video from internet while doing nothing else:
I really can't explain this one. After 2 hours wandering in internet looking for stuff like gameplay videos and tv series it shut down. Boom! No reason. Everything was cold at touch (motherboard, cpu, graphics, ram). I tryed to restart and it shut down again even before loading Windows. Waited 10-15 minutes, tryed to restart and again it shut down before loading Windows. Then i detached energy, waited a couple of minutes, and then it started properly with no problems at all. Then i started wondering... what does change after i detach energy for 2 minutes that doesn't change after 10 minutes of staying off? The only thing i could think is ram. But if a ram block is damged problems should occur in the moment it starts being used. Still sometimes i got over 4 gb of ram under use without problems. Then questions are
5) What can be the cause of this unexplainable chain of shutdowns?
6) Is it possible that just a portion of ram is damged, so that it shuts down only when ram usage is high enough to reach that portion (idk how it works, maybe i'm just saying something absurd)
7) If that's possible how should i test it? Using only one block a time and trying to bring it at 100% usage till computer gets stuck, and if it shuts down i know which block is the cause? How do i fill the ram like that? xD (maybe monitoring it, so high-demanding fullscreen-only games are excluded)
Asus ROG Crosshair V formula z
AMD FX-9590 Eight-Core Processor
Sapphire AMD radeon 2gb GHz 7870
Windows 10, 64 bit
Windows XP Professional
Ms Dos <<that one doesn't cause temperature problems neither it reaches half gb of ram usage of course
