I think i broke my pc with prime95 plz help

[MrMcyeet]

So a buddy of mine said prime 95 would explode his pc, so mr me was all like heh, lemme dl it and see, and i left it on for like half an hr on accadent, oops, its now at 100c, so i killed it from task manager, deleted it, and shutdown my pc.  Few mins later, boot up, and straight to 100c, so i goto the intel extreme tuning utility ( i only mess with the basic tab, never touched the advanced tab ) and drop the stuff down below stock and STILL 100C.

 

So i shut down and goto the bios bc idk, i wanna fix it. And the bios reads 90c, like WTH? 

 

So i then unplug it, goto bed and wake up just now to boot it up, instantly 60c, and not 5 mins later, 100c AGAIN?? BRUH... What do i do tech gods? Plz yall help me.

Make sure your radiator pump is running, and try re-pasting the thermal paste.

Your pump likely failed. Prime95 is harmless in it of itself

Yes ^^

Not always, some versions can damage Haswell-E and a few other gen CPUs. I haven't heard of any problems like that on 8th or 9th gen though.

Check paste on the CPU (replace if it seems necessary), and verify that the pump is running.

 

As aggressive as Prime95 is in itself it won't kill your CPU so long as the heat generated is kept in check.

How do i check if the pump is dead, and will corsair replace it if it is dead, and in warranty still?

If it's under warranty - yes.

 

Easy - use the Corsair Link software

That's what you use the latest version

Unless they changed it to not push AVX/AVX2, then the latest version will still push my CPU too hard and possibly damage it (I run a Haswell-E 5820K). Again not applicable in the OP's case, but Prime95 can be a risk for some platforms.

It shouldn't kill Haswell cause I've run the latest version on a 4590 and 4720HQ - both are still alive after several hours of prime

AFAIK its the MB that usually goes belly up and takes the CPU with it.

 

The OP though, they likely just have a clogged block or dead pump.  Not the first dead H100i that I have seen.

 

This is why I refuse to use a CLC on any of my builds.  More parts to break and if the pump goes south its not easy to replace at all.  While you can just swap fans if you get a large air cooler with standard fan sizes.

I'm on Haswell-E. HEDT chips, run hotter but safe max temp and voltages are lower. The issue is Prime95 pushes them much, much, much harder than they ever need to be and that can be unsafe. They pump out a hell of a lot more heat than any normal Haswell chip. Even short runs of Prime95 burst mine to over 85C on a custom waterloop, ASUS Realbench doesn't push it much past 60C while accomplishing the same thing.

From what I read it's the CPU being pushed too hard, most X99 motherboards are pretty beefy. Something like the 6950X could maybe toast some, I highly doubt that though unless it's under terrible conditions (aka no airflow over the VRMs at all).

Well - if it makes you feel better, my 8th gen i7 hits 90 when rendering on high end air

True, those bois have always been hot (but then my 8600K didn't hit much above 80-85C on an NH-D15S at 1.35v or more inside an S340 Elite with SLI 1080s). Being that hot is probably due to the smaller contact point for a cooler, 1151 CPUs are tiny compared to 2011-3 lads. Even 1366 CPUs are massive by comparison.

Nah - it's the snot paste and process pushed way out of the efficiency curve

Guys can push 5Ghz on water with well binned 5960Xs and those are on a larger, hungrier process, the clocks shouldn't be the issue. The oof paste doesn't help though, would be interesting to see how a soldered 8700K with an IHS the size of a 2011-3 CPU did. The X299 lads are big boyes but they're also massive core counts, and only the 9000 series ones are soldered (kind of a meh solder job as well IIRC).

Latest Prime95 supports AVX-512. If your CPU supports that, it is WAY hotter than AVX2.

 

Userland software should never be able to damage hardware unless the hardware was inadequate. Specifically the only risk is for those doing extreme overclocks and inadequate cooling.
