System shuts down

[ITGL72]

Not sure how to troubleshoot this. Few weeks ago I built a PC for one of my kids. Mainly plays minecraft. Its worked fine, he has played the game and its run well. Now, I changed the cpu heatsink and fan to a ARCTIC Alpine 64 GT Rev. 2 CPU Cooler. The stock one that came with the AMD got *very loud* so I changed it to this.

System is an AMD FX-8320 Vishera 8-Core 3.5GHz (4.0GHz Turbo) Socket AM3+, GIGABYTE GA-990FXA-UD5 motherboard, CORSAIR Vengeance 8GB 240-Pin DDR3 SDRAM, with an AMD HD Radeon 6900 series 2GB video card.

Used an old case I had laying around. Everything fits fine.

OK, so after I put in heatsink and fan, i fire up the game RUST. I put the panel back on the tower and walk away. I come back, the computer is OFF. I try to start it up, it dies again on bootup and asked me to restore windows. I did, it came back OK. I took side panel of. Started again and played RUST for about 15 minutes. Seemed OK I put side panel on, within a few moments system shuts down.

So now I am thinking something is getting too hot? or the case is weird or has a short somewhere to a component?

I had MSI afterburner running and didnt notice anything too out of ordinary but maybe Im missing something? GPU was about 80 C and CPU was not spinning fan that high from what I remember.

Im fine to buy another case. I hate to take it apart again but I dont want to hose the newer components I bought. Not sure if there is anything else I can do to troubleshoot. Theres no log I am aware of that says "Shut down due to ......." etc.

What do you guys think?

 

[ITGL72]

Well I just ran RUST in window mode and had MSI afterburner in the corner. The CPU got to 85 degrees C. I think that is too high and that is what is shutting it down.

Just so that I'm clear, the system shut down a few seconds after putting on the side panel? That would indicate there is a heat issue to me. An electrical issue would be instant.

What kind of fans does the case have? Are they spinning?

 

[VirtualLarry]

Get a new case, one with both intake and exhaust fans - sufficient cooling for an FX CPU.

I'm using a RaidMax Cobra case, it seems pretty decent.

 

[LTC8K6]

CPU was not spinning fan that high from what I remember.

The cpu fan should have been screaming if the CPU was that hot.

I changed the cpu heatsink and fan to a ARCTIC Alpine 64 GT Rev. 2 CPU Cooler. The stock one that came with the AMD got *very loud* so I changed it to this.

When you remove the original cooler you should use a coffee filter and 95% alcohol to remove the old TIMS(thermal interface material). Once dry wipe again with clean filter apply new TIMS on the CPU then install new cooler.
IF you added a better cooler and yer temps went up, something is a miss! It wasnted shutting down before. why did you add the new cooler to begin with?

Yes, a few seconds but at least less than a minute I put the side panel on and it seemed to have shut down. I actually watched the cpu temp utility get up into 80C area and then it shut down. I ran the game in a windowed mode to observe the utility.

My case is OLD. It is roomy but old and Im thinking maybe I cut the corner on this. It does not have a fan on intake just exhaust, it has two for exhaust. Fans are just regular 80mm fans.

I never ran RUST for any period of time before with the original heatsink and fan, just a quick run around to see if it worked. Like I said, Kid played minecraft on it for hours (before I kicked him off on weekends) and the fan was LOUD on CPU. SO I changed it. This seems quieter, but alas.... I seem to have discovered something.

I did that, I removed it with several coffee filters and alcohol. I have done this a few times before with no issues.

Added it because the fan seemed LOUD. Maybe it was working harder than it should.

Looking at replacing the case with this:

This is probably your culprit right here. A case with a severe negative pressure (i.e. only exhaust fans) can have unexpected hot spots. Getting a new case is an option, but just moving one of your fans from exhaust to intake may be sufficient.

 

[Puffnstuff]

Electrical isn't always instant and a ps loses output as it heats up. I'd replace the ps first then go from there but if heat is an issue then you should replace the case with a unit with good air flow.

Well, case isn't really easily able to put front fan without probably breaking some plastic. I rather just get a better case and a better heatsink/fan and have some piece of mind. I'll just put this nugget away in the experience category and spend a few hours getting the components transfered over.

 

[daveybrat]

Of course your system is going to shut off on you when you replaced that heatsink.

The stock AMD heatsink is rated for 125Watt cpu's.

The Arctic Alpine heatsink specs:

Compatibility
AMD Socket:
FM2(+), FM1,AM3(+), AM2(+), 939, 754
Max. Cooling Performance:
70 Watts

http://www.arctic.ac/us_en/alpine-64-gt-rev-2.html


You actually downgraded the heatsink to something that can barely cool an FX Quad or Six-Core cpu, let alone an 8-Core.

Pick up a CM Hyper EVO and it'll be nice and quiet.

 

[ITGL72]

Yeah, silly me. I saw it was good with am3 and thought that it was all it needed.

 

[ITGL72]

I am so disheartened right now.

I swapped out the parts into a new case and added the cpu cooler. Here is what I changed into:


Rosewill CHALLENGER-U3
http://www.newegg.com/Product/Product.aspx?Item=N82E16811147060

Cooler Master Hyper T4
http://www.newegg.com/Product/Product.aspx?Item=N82E16835103182

At desktop, it seems very cool. 20C or less. When I load a game or run 3dmark demo its about 30, under 40C so cooling temperature no longer seems like an issue.

But it still SHUTS DOWN. I have to pull the power cable for a moment out of the Power Supply, and then put it back in for the power button on the case to let me start it up again.

So now I'm like, what do I do with this thing? All new parts, something is making it shut down under game load (or 3dmark load) and the temperature is fine.

Rest of my setup in this PC:

Well, any suggestions for a next step? i wish I could look at a log that would tell me, this is why this is shutting down.... ugh....

 

[MongGrel]

I'd still stick a Hyper Evo for a CPU cooler in there myself.

Minimum.

 

[ITGL72]

I'd still stick a Hyper Evo 212 for a CPU cooler in there myself.

This thing isnt over clocked, its not even hot. I have an EVO on my other PC and its great but this T4 is pretty damn good as well. Its not running hot on the CPU at all.

 

[MongGrel]

NM.

 

[LTC8K6]

Video card?

How hot is it getting? See what temps the GPU is hitting?

Earlier you wrote that it was at 80C in the old case?

 

[ITGL72]

Have to see, video card can shut down a PC?

its an XFX AMD RADEON HD 6950 2GB

 

[ITGL72]

NM.

Not to derail my communications here but you replied with "K" then changed it to "NM" and I see you have 17,000+ posts. Ahh, like I said I dont want to derail but... ahhhh NVM, all good. Peace...

 

[Valantar]

Is the fan on your PSU running as it should? Sounds to me like it might be overheating and hitting a thermal shutoff point. There wouldn't be any indication of this in anything in Windows, which matches your issues. Also, there would be a world of difference between an open and closed case for PSU cooling.

 

[ITGL72]

Well it did it with the case side on, and off.

I have access to a ZU-1000B power supply. I'm planning on swapping that out tonight.

 

[redzo]

But it still SHUTS DOWN. I have to pull the power cable for a moment out of the Power Supply, and then put it back in for the power button on the case to let me start it up again.

To me it looks like the system is suddenly loosing power. A lot of pc's exhibit this and it is indicative of a system power loss/failure. This could indicate that there is something wrong with your power grid(try to plug it into another power outlet maybe?)or corsair psu. A possible overheating scenario is still probable as a system power off like that might be caused by a over-heating protection system.

 

[ITGL72]

Well, the CPU certainly isn't getting too hot. Its roughly just under 40C when the load goes up. Im not sure what the case temperature ambient is since I was focusing mainly on the CPU. But its not nearly as hot to the touch as it was in the previous case. Hopefully tonight Ill get more info or maybe its just the PS needing to be swapped. There have been computers plugged into this power outlet before. Unless my old surge protector is a weak link along the way too. Now thats getting granular.

What do you guys think?

If you've been precise in your statements, your problems started after changing the stock am3+ fan. It seems too uncomfortable to take this as a pure coincidence. I believe that you are missing something. If you are certain that everything is in right order after your final assembly, you should go back exactly after your problem became obvious. Check the motherboards heatsinks! I don't know, maybe some MB heatsink got loose. Just don't loose it and dig deeper. Unless you broke something or something got broke in the mean time, there's should be nothing keeping you from getting the system back to its initial stable state. It's more up to you to figure it out.
