CPU fans speeds up then shuts PC OFF

New Reply

I am in need of some serious help as I not only have a serious issue that restricts me from using my computer but I would also love to learn how to solve this issue at hand. Please read everything.

I recently bought my brand new Asus desktop computer last year…
ASUS DESKTOP PC AMD FX-Series, FX-4150 (3.8GHz) 8GB DDR3 1TB HDD Capacity Windows 7 Home Premium 64-bit.

Now, as of before-yesterday I purchased RAM + Graphics card to update and to play games on my computer with smoother performance.

RAM = 1 x G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-

Graphics Card = 1 x ASUS Radeon HD 6450 EAH6450 Silent/DI/1GD3(LP) 1GB 64-Bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Ready …

Long Story Short: Before putting on my new computer parts I took out my fan, the silver thing under it, and even the processor. I cleaned the ENTIRE fan and motherboard so there is little to no dust, then…

I put on these new parts on my computer and as I turned on my Asus desktop it turned on normal but 5 seconds later the FAN sped up 10x faster than normal and in less than 30 seconds the entire computer shuts down.

After I bought and installed my new RAM + GPU my computer will not run. The fan speeds up 10x faster than normal, makes a loud sound then the entire computer shuts down automatically.

Have I done something wrong? What must I do? PLEASE HELP ME! :confused:
(I have enabled email notification in case anyone posts any further questions I will answer immediately!)

Your description sounds like it may be overheating.
Are you certain you properly applied heat sink compound when repositioning the cooler on the CPU?

It sounds to me like you need to go back in and recheck and reseat your CPU cooler to the processor.
We hope you didn’t reseat the processor improperly, that would be a fantastically expensive mistake for which there will
likely be no coverage for.

Another thing…

You should NEVER have done all that work at once, now you [theoretically] face the challenge of
troubleshooting the newer components you just added too.

CPU fans have a small blob of thermal conducting compound on the surface that sits on the CPU. If you cleaned that off your CPU will overheat and shutdown.
You can buy new thermal compound.

I’m not seeing much promised rapid response from the OP.

I had no internet for a few days.

My computer is up and running although my fan is SUPER LOUD and it doesn’t stop running whenever I have a game up…

It’s incredibly loud but at least it works so now i’m stuck with another problem although this seems like a minor issue.

New problem: MY FAN

I may have re-seated it incorrectly but now I have fixed that (took it out again and put it in the right position).

What suggestions do you have?

edit: My processor can only be positioned in one way, so there is no way to make that mistake, although the silver metal part (CPU cooler) is what I had positioned incorrectly + my fan. The processor is fine, but the fan doesn’t stop running and therefore the sound is EXTREMELY LOUD and obnoxious.

I would suggest getting a new fan. This would be a quick, easy, and inexpensive solution to your noise problem.

Did you clean off and use new thermal paste?

This is still classic thermal overheating symptoms. That HD6450 [sorry I should have noticed in the original post] should not be running that hot unless you overclocked it assuming it is at idle.

Unless you did not reapply thermal paste, did not confirm that all fans are working then PaulT is correct the next step is adding a fan to the case to try and pump more hot air out the back/top, or to the front to pull more cool air into the case. If the temps you posted are at idle 65C is too warm. How warm is the ambient air of the room the PC is operated in?

One test of this would be to temporarily open the case and position a table fan blowing directly into the case and demonstrate lowering temps and proper running of the PC. That would indicate you have an air flow issue within the case.

What is the model of the ASUS desktop?

Lastly, the HD6450 is a wonderful video playback card but a poor gaming card despite what marketing might say. What exactly was your old graphics card?

….We also have to figure out why my games aren’t 100% lag free. I mean the GPU is 1GB so for a game like League of Legends or even WoW it should be fully smooth.

Assuming you mean the original games WoW should run okay on a 6450, LoL on low FPS too. But if temps are getting so high as to automatically dial back the CPU and GPU to keep them from burning up no setup will run them without lag or thermal shutdown. I think solving this overheating issue may clear up this other issue. But a 6450 won’t perform miracles. The FX4150 is a good cheap gaming CPU, but at minimum I’d pair it with a cheap low end gaming GPU like the GTX750Ti or R7 260X.

The temp readings in your screenshot are not particularly high, but I wonder if the system was under load at the time?

When I check a system that I think might be overheating I run “Heavyload” ( http://www.jam-software.com/heavyload/?language=EN ) and SpeedFan ( http://www.almico.com/speedfan.php ) together for at least 15min while keeping an eye on SpeedFan’s temp readouts.

SpeedFan’s reading are not much to go by if the system is not working hard.

I think you may be on to something, I just downloaded Heavyload and am running a scan right now to see about it.

Also, I don’t know how huge of a deal this is, but I did not apply thermal paste, in fact, I don’t even have any thermal paste/compound..which is the best to buy? Does brand matter in this case? Link me.

Also, I can only play League of Legends if it’s on the lowest graphics settings possible, otherwise the game will lag so hard I can barely move. How is this even possible when I just bought a DDR3 graphics card based on such a simple game? I thought this would make me be able to run lag-free on high graphics whilst playing comfortably, but no!

I apologize in advance from the late reply, but this topic is very important to me so I had to bring it back and will keep it alive for quite a while.

This is the first time I’ve owned a PC and that I will invest parts and time into. I’d really like to learn everything about this whole journey while upgrading my computer, and therefore I couldn’t thank all of you enough.

Next on the list is buying:

– CPU cooling fan
– Processor

When you are adhering a heat sink to a chip, you MUST use thermal paste. It makes sure that the heat is well-transferred from the chip to the heat sink.

If you are mounting a fan, but the fan does not incorporate a heat sink, then you don’t need thermal paste. However, if you are using a “fan heat sink“, then you need thermal paste.

Arctic Silver 5 is a very good thermal paste. Here is a comparison of several different thermal pastes.

It’s been running for over 7 hours…what now, man? What am I expected to see here?

I’ll be sure to buy an approved one as soon as possible, meanwhile am already investing in a new CPU cooling with 3-6 heat sink pipes.

Check the BIOS for CPU and motherboard temps and if they’re good, see if there is a setting for speed stepping the fan depending on thermal stepping.

Also, here’s the weirdest thing of ALL…

My games now have lag ever since I put in my new graphics card

Like, how in the hell does that even happen. There is no logic in that. It doesn’t even make sense.

That happens when something is not right.
You haven’t sorted the temperatures out if the fan runs very fast. Install SpeedFan or other hardware monitor and check the temperature – it should be 70C or less.

cheers, Paul

Your new GPU is a HD6450?

Yes sir, that’s what it says. Why are you asking?

So now the question is, which fan should I buy that is under $100 from Newegg.

We also have to figure out why my games aren’t 100% lag free. I mean the GPU is 1GB so for a game like League of Legends or even WoW it should be fully smooth.

Maybe you need an additional case fan to move more air through the case for the CPU/GPU fans to use. Do you have any case fans?

cheers, Paul

Your temps look a bit warm. I hope that’s not at idle.
But yes, a properly ventilated case with enough fans to move the air out is a must.
Otherwise you may end up with fans running at max. capacity and still not doing the job.
