Computer keeps shutting off.

[mindlogiczero]

just doing some reading
http://www.overclock.net/air-cooling/529915-how-these-temperatures.html
they are saying his voltages are crazy high.

my cpu core is 1.7v
and my +3.3v is 3.4 volts according to everest. dont know if this means anything in regards to the heat just thought i would share. since im with dell i dont even think i could fix that issue, think it'd need to be done in bios.

also note, computer completely froze after restart twice today, out of no where soon as it restarted and everything loaded. i restarted after the freeze both times and all was well and didnt come back. only came back after i restarted again then just fixed by restarting. hope this doesnt mean anything bad.

Use CPU-Z to measure your core voltage, for that CPU it should be 1.3 to 1.35V. "If" your cpu core is 1.7V, there is a prime candidate for your overheating and shutdown issues.

Noticed that in the OP you stated 2.9GHz, slight overclock as this processor stock runs 2.8GHz.

ah i guess like the temps everest seems to be wrong. cpuz says 1.325.

so i bought new paste, this new paste texture is alot easier to spread then what i was using and can see how it could spread itself over the whole cpu. the other stuff was so hard it would just stay in middle. heres prime 95 after like 15-20 mins or so?

mainly stayed 69c-70c and took awhile to get there. so it seemed a little better atleast i think.

i traded psu instore for this heatsink http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3071635&Sku=T925-1199 but it rubs my psu and wont fit so i need to go back to trade it for a different one.


what would help temp the most, my 120mm side case fan thats just about over my cpu, blowing in or using it as a exaust?

1) I mentioned above that the Coolermaster reviewed as the best of the three you linked. Looks more compact as well.

2) Temps are a *lot* better now, mainly because they seem stable at max load. I don't know if your mobo is set to go max fan at 70, or if that's the best the cooler can do. Anyhow, the stock fan prolly can't do too much better unless we get more air movement *through* the case (lowering the ambient temperature inside the case).

3) Fan direction: The fan in the rear of your case should be on exhaust. When you install the new cooler, it should blow towards that fan, moving the hot air to the exhaust, and out. I don't see a side case fan in your pictures. Did I miss one?

 

[mindlogiczero]

those pictures i took i actually googled my model. i will take pictures of mine now.

as for that one heatsink, i dont believe they had that in the shop + a sale guy promissed the one i got would fit.

147 x 92 x 143mm thats the size of trhe one i got, 120 x 120 x 158mm size of the other. also the coolmaster v8 one is a 4pin and my motherboard connection for the cpu is a 3pin.

in the size 0x0x0 which would be the one to check for the area towards the psu?

 

[Twoboxer]

Dunno - what cooler did you end up with?

but its like a good half a inch or maybe lil less? trying to go where psu is.


dont laugh at my amazing quality pictures or where i cut out the metal that was guarding the back exhaust fan lol. side is 120mm about directly above the cpu blowing down, front fan is a 80mm blowing in, exaust is a 92mm. side and front are hook straight to psu so going full speed i believe. think ill swap the exaust tonight with a 80mm i have and hook it to psu so it can 2 go full speed. since being dell wont let me control them with speedfan.

No laughs from here - that's often the only approach to dealing with a Dell lol.

Anyhow, the guy prolly promised it would fit because you can mount the heatsink "sideways", ie, blowing at the psu. Gut tells me that's not totalliy ideal, but since you have two fans exhausting there (psu and back fan) it might be OK. Also, if your side fan is a little *below* the cpu (towards the expansion slots) that might work out OK as intake too.

With the vent below your side fan, if you turn the side fan to exhaust, I'd guess it will mostly exhaust cool air from the front fan and vent, fighting your two exhaust fans a bit, and probably reducing the amount of air they can exhaust - which wouldn't be good.

However the best way is not to theorize, but to test.

err, last post deleted. so prime 95 sat at 64-65 stable 67 peak up untill when i stopped it at test #6. going to redo heatsink just to see how well it spreaded/make sure i didnt use to much to further help temp. im thinking its safe to say if these temps stay like this i could safely do without aftermarket heatsink?


redid paste and switch back to 92mm exhaust, recieved the same 64-66 prime 95 constant lvl.

Have you made sure you have the latest bios and reset cmos

latest bios is up, what does reset cmos mean? i know its when you take that battery thing out but why do i need to do that/will it reset my bios to default bios? if it wont recognize my chip

Careful - sounds like he read opening problem only, not the thread.

Yes, those temps are definitely fine for 24/7 operation. And it is unlikely you will run anything approaching Prime95's load for any length of time. I didn't see how long you ran prime, but run it for two hours. Same results = no new heat sink

I'd advise running RealTemp out of your Startup folder - at least for a while. This will let you see your core and gpu temps on the task bar where you can watch and get accustomed to what they "should" be.

Nice working with you - good luck!

sorry for not being the smartest, was my first cpu ive ever switched. lol, the power cut offs scared me and i believe it was the cpu heat doing it.


thought id let you know i got http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2478160&CatId=493
this heatsink today and switched side fan back to intake, been running prime for over a hour and web surfing, messenging, and on steam, max has only been 48c, but stays around 45c. i think the idle was around 35c?

thanks for all the help, appreciate it. i started thinking my cpu was faulty when i seen those temps =\.

 

[Twoboxer]

You stuck with it, and you got it lol.

Anyhow, the downdraft cooler you bought is very good in its class.

HOWEVER, a downdraft will never cool as well as a rifle (standup) cooler.

BUT, in your case with the side fan . . . its gonna work out very, very well. And it will cool your mobo better than a rifle, too.

Nice choice.

pics, hope i dont need to get to hdd, psu or ram before i upgrade pc, was a pain to get this installed. =]
