My Dell XPS 2720 frequently shuts down and reboots on its own. When this happens the CPU fans are running high. There are no warnings just goes to a black screen and reboots. I'm thinking one of the fans is pootched or maybe the power supply needs looking at. What do you folks think? Any ideas are most appreciated. Thank you.

✔ Best Answer
sounds to me like a thermal shutdown, perhaps the cooler came loose a little or the thermal paste dried up completely & cracked, causing high cpu hotpot temps, triggering a thermal shutdown.

could you run something like realbench 2.54 or higher & tell me what the max temperature is after 5 runs of H.264 Video encoding or if it spits out any errors?

DAMN

that really bad, Must be TJMax hit, causing the cpu to shutdown the system to prevent damage

it could be 1 of 3 things or all combined;
1, CPU heat-spreader is not mounted tight enough (anymore), or the thermal compound is cracked(too old)
2, the PC case is somehow recirculating hot air.(maby a dead fan or too?), (or does the case have no room to suck in & exhale air?)

3, the voltage is set too high, but you can forget about this, because the only way to do that on your CPU is by using XTU (which you probably do not know about)

Best bet is to replace the thermal paste and re-seat the cpu cooler.


P.S. mine hits 53 max, after delidding tho, 76 before, using normal paste(which is fine)

Awesome thank you. It has plenty room on my desk and isn't near the wall or anything like that. I'll take it into the shop and tell them what you think it is, again, thank you so much for your help

Overheating definitely.
If you have not cleaned it out for a long while, begin by picking up a can of compressed air like Dust-Off from a computer or office supply store. Open any easily openable ports and blow out all vents. If it has been a while, it can get messy. It appears to be an all-in-one so i am not sure how easy it is to completely open it up but that is the best way. Make sure that the fan turns easily but avoid allowing the compressed air to overspin the fan.

You have to be a little bit crazy to keep you from going insane.

An A-I-O is somewhat similar to a laptop in terms of hardware but the inside of the case isn't as cramped. I posted the service manual so you can see how to open it up for cleaning or whatever else needs to be done. My guess is it's dust clogged or the cooling fan is bad. I doubt it's a thermal paste issue. See page 19 of 147 for the board layout.

Hi Alpha, I agree with Riider that it is probably an overheating problem caused by dust.

In these devices, dust particles have a tendency to be sucked in, but are too large to exit through the cooling matrix. Eventually quite a wad builds up.

Problem is compressed air cannot always break the wad up and danger is the wad is just blown back towards the fan, possibly jamming it.

To remove properly often needs access to the Fan - Cooling Matrix path. You may be able to find a Youtube Video showing how this is done for your Dell.

As a matter of interest, where (City/State) are you based? I am in West London.

Good Luck - Keep us posted.

I'm in Canada, Northern Ontario. I took the back off the computer yesterday and cleaned out any dust I could see on the 3 fans. It didn't shut down once after that. I left the back off and will put it back on today assuming it doesn't shut down this morning. Thank you, everyone, for your help.
