psu, cpu, mobo

By SystemCheck ·
one of these is broken had pc for about 3 1/2 years then starting early last week it started to freeze up on me. Then it became more reoccuring so i reinstalled the OS to no prevail. Thats when i noticed the heat, mobo gets to about 120 F, cpu 141 F, gpu 161 F this is with the new cpu fan running at 2000rpm. Without the new cpu fan (the old one in place) the mobo is 130 F, cpu 170 F, gpu 161 F, that is when is freezes on me. From the test i was able to do the ram is good and the gpu is good. Last nite inserted a different psu but test was inconclusive due to the fact my boot files went missing but still powered on my no fans then (bad psu idk). I think it may be the psu, cpu, (hopefully not) the mobo. What is broken?

That's a wee bit warm

by cmiller5400 In reply to psu, cpu, mobo

The CPU is probably overheating at 170F. What CPU is this? It really depends on the make/model for accurate temp thresholds.

I'd be making sure that you have proper airflow in the case (pull in air in the front and push it out the back) some of the fans may be backwards creating a wrong airflow pattern. Also make sure that you have proper coverage on the CPU/heatsink of thermal paste. Too much is bad and too little is bad.

cpu type

by SystemCheck In reply to That's a wee bit warm

its the intel e6850 (core 2 duo 3.0 3mb)

dont believe its the airflow was running fine for like 2 years in its previous state just turning on facebook increase cpu temp 20 F.

Way too hot for operating temps

by cmiller5400 In reply to cpu type

See the link at the bottom, the operating temp is 41F - 161F. I'd replace the stock heat sink with a more "souped" up one. I saw on a quick Google search that the stock heat sink wasn't sufficient in the posters opinion.

sorry to tell you

by SystemCheck In reply to Way too hot for operating ...

but these number are with an aftermarket, solid coper heatsink and yes i have applied the thermal paste on correctly and reapplied it correctly (pea size).
also just got phone call that my hdd is acting up now might be from heat dont know.

Don't know if i mentioned it but

by cmiller5400 In reply to sorry to tell you

Have you double checked to make sure that the fans are running in the right direction and didn't accidentally get reversed?

its possible

by SystemCheck In reply to Don't know if i mentioned ...

got two case exhaust(top of case and side of case, one case intake (back of pc) one cpu blowing toward hdd

wow - high temps

by Snuffy09 In reply to psu, cpu, mobo

have you tried putting a fresh dose of thermal grease on your cpu?

are all your fans clean and working ok?

about freezing up, before you said you checked the RAM i would have thought the ram was bad, how did you check the ram? i would swap in a stick that you know works from another system.

Are there any errors in the event log? you could have a harddrive going bad.

if your system has been over heating for awhile now without your knowledge you may have a few damaged components. I have seen small form factor towers that got too hot and capacitors burned/exploded leaving a brown liquid behind on the motherboard... lovely!

high tems

by SystemCheck In reply to wow - high temps

fresh thermal paste have been applied

pc clean, fans operational

ram i do have two spare sticks i can use

nothing in the error log, hdd thought about dont know how to test

mobo doesn't look like it blew up

by ---TK--- In reply to high tems

you have a nice aftermarket CPU Heatsink...

Just wondering: do you have speedstep enabled in the bios? also is the CPU fan in the correct slot on the mombo? Sometimes the system will increase/decrease RPM's based on thermals...

(edited: I can't spell today..)

cpu fan

by SystemCheck In reply to plus

the cpu fan uses molex connector which runs off the side case fan which runs of the secondary dvd burner (rarely used)
