CPU slow, fan running at 4000 rpm

Luis Morales · Aug 24, 2013

Hello,

I recently experienced some issues with my computer.
While playing Guild Wars 2, my computer went into overdrive (i went from 90 fps to 4), means, task manager would show the CPU running at 100% and the cpu fun is clocking 4000 rpm.

I have ran AVG antivirus, Iobit Advance Care to no success (they all showed no errors)
I ran AlienAutopsy's PC-Doctor check up and all my hardware showed as passed.

I just updated the BIOS to A07 and reformatted my HDD to reinstall windows, and even tho my computer isnt showing the CPU at 100% anymore (13% atm, while running windows update) the fan is still clocking 4000 rpms and the computer still seems slow.

This are my system specs
Alienware Aurora R4
Windows 7 Home Premium 64 bit Service Pack 1
intel Core i7 - 3820 @ 3.60 GHz (i believe my computer lost the overclocking after the format)
8 GB RAM
nVidia geForce 560 Ti

Any help would be amazing!

A bios update gets rid of any previous bios settings so an overclock. Not sure y u formatted and reinstalled windows, but ur OC def was set to default.

That cpu is quite hard to get to 100% unless ur stressing. If the cpu fan is running at high rpms its not because the low use on the cpu, its the heatsink that is being used, it is either coming loose or is no longer contacting the cpu heatspreader and is causing poor heattransfer and the fan is trying to keep up with heat being produced

What would you recommend me to do? Should i open my case and make sure the fan is not loose?

lazyboy947 · Aug 24, 2013

yes do that and not sure if its stock cooling or aftermarket cooling and if stock then not sure what u can do its pretty straight forward, but if its aftermarket make sure the screws are tightened snug but not too tight

Hello lazyboy947, coming back with an update.

I have removed the CPU fan, and i found the thermal paste pretty dry. So i replaced it.
I cleaned the fans as well as the inside.

So far this is what my sensors are registering:
Internal Temperature 24C
System fan 3075 RPM (it started at 1800, then slowly increased to over 4000, now it has slowed)
PCI fan 1800 RPM
CPU Pump Running.

My CPU is running at 0% while idle, and the memory is at 30%.

Im going to install guild wars 2 and see if my fps is still low.

Will post more updates later.

Back again with some updates.

I tried to update Guild Wars to end up having my computer shut down itself.
Right now im running nothing but Google Chrome and my fan is running at 4000 rpms.

Im running out of ideas and getting quite frustrated.

lazyboy947 · Aug 24, 2013

What are ur specific specs?

Luis Morales · Aug 25, 2013

lazyboy947 :

Windows 7 Home Premium 64-bit (6.1, Build 7601)
Alienware Aurora R4
Bios Date: 10/26/2012 Ver: 04.06.05
Inter Core i7-3820 @ 3.60 GHz (8 CPUs)
8192 RAM memory
DirectX 11

Am i missing something?

A little update:

I have downloaded CPUID HWMonitor, my 4 cores are registering temperatures at 70 degrees while idle, i dont suppose this is normal.

lazyboy947 · Aug 25, 2013

When i asked for full specs was more for a detailed model etc and including the cooler as its ur main issue would be good to know what it is. At stock clocks 70c is terrible at idle lol.

Hello!
Sorry for coming back so late, work and stuff, it gets crazy out there.

So i checked the heatsink, i cant really point a brand, it has no stickers besides the ones from Dell

lazyboy947 · Aug 27, 2013

Is it a liquid cooler? if so the pump or the radiator might be bad, and those have a lifespan of about 5years as liquid will evaporate if i remember but most likely the pump, if its like any other liquid cooler the pump is connected to the board and the fan to the pump so the board regulates the pumps speed by temp and then the fan speed as well, so with high pump speeds equal high fan speeds

Luis Morales · Aug 27, 2013

Yes, it is a liquid cooler.

Though is only one year old :/

lazyboy947 · Aug 27, 2013

so u re applied paste? made sure u used the right amount? also that its secure? case has good airflow? radiator fans are moving air? Did u try another fan attached to the radiator as it seems heat is causing ur cpu to throttle which lowers performance, and again bad waterblock contact to the cpu isnt good, old paste, a badpump or fan

Luis Morales · Aug 27, 2013

lazyboy947 :

This is the inside of my case.
For what i have been told, this seems to be bad (architecturaly speaking) because there is a bad flow of air, or so im told. i can really now that i opened, it seems quite small.

I just bought a Corsair Hydro H60 along with some Arctic Silver 5 and hoping to get it tomorrow, i will replace it and give you more news.

For the paste, i followed a guide on youtube, i applied a pea size of paste on the cpu the spread it evenly on top with a business card.

Also, before i took out the heatsink, i managed to run an Intel Burn Test. From what i read, this can be useful to know if the cpu is bad. Out of 10 tests, i got my results all the same numbers (which i read on the forum that same numbers is good)

The only big movement my pc has had was when i moved in to my new apartment, tho this was 4-5 months ago and this issue just started during last weekend. Maybe this had something to do in the long run?

I will post my results tomorrow or Thursday, depending when i get my new cooling system.

Luis Morales · Aug 29, 2013

Hello everyone!

Back with some updates.
very sad

I just installed my new Corsair CPU pump, just to have my computer not turn on. the power is going in, it seems for 1 second is gonna turn on, then theres nothing, complete black.
Im not sure if it might have something to do with the fact that my heatsink has a 3-pin connector and i only have 4-pin conectors in my mobo.

Also, while taking out my CPU to clean the old thermal paste, ive noticed that some of the pins in the CPU socket are bent, (i see like little holes in the socket, and when i pass my finger i can feel some of the bent pins.

I have decided to take out the mobo, and attemps to repai those pins.
Otherwise i need a new mob....

Luis Morales · Aug 30, 2013

[/quotemsg]
when you run your hand over the socket holes you feel pins sticking up ?[/quotemsg]

Yeah i do, i can even see some pins stuck in the bottom

That is not right ! look at your cpu pins do you see some missing ?[/quotemsg]

Well its really hard to tell, those freaking pins are small, if not microscopic.
I managed to spot some of the pins stuck at the base of the socket. I didnt really know what would be possible. Maybe bent sidewards, but all the way down?

Luis Morales · Aug 30, 2013

buy a new cpu??
Is my cpu no longer good?

Luis Morales · Aug 30, 2013

tourist :

Well, when i checked the cpu i can say im 95% i didnt not damage it.

CPU slow, fan running at 4000 rpm
