New PC - fans blowing constantly and loudly

Hi, I'm new here. When researching some issues I've been having, one link brought me here and there appeared to be a lot of helpful threads, but none that really addressed my issue (that I found).

I recently got a new computer (mid-late July) and about two weeks ago, some or all of the fans started blowing extremely loudly. I did a little light research and determined the power supply might not be working correctly and replaced it with another, bigger one I had. After doing this, the problem disappeared for a week. Last night, however, it started again - more quietly that it had been before, and for a shorter time. Now it is happening constantly, even if the computer is sitting idle.

Does anybody know what could be causing this and what I need to do to fix it? What information might you need to diagnose the issue?

Thanks in advance.

Thanks for the reply.

You can find the machine's specs there. Like I said, I replaced the PSU with a 650W and that seems to be the most common problem, both on newegg and elsewhere. Thoughts?

Just type them. Normal temps without loading the system would be fine. If you want to stress your CPU to 100% and post more results that could be helpful in comparing.

Bad power supply with a new pc is not unheard of.
So far the past 20 years when buying a new pc with a bad power supply?
I ran into 4 computers like that. Not bad odds.

Now when just buying the power supply alone then I always demand to test it at the store so I do not have drive all the way back wasting time and gas no matter how nice they speak about the in-store warranty.

Well first of all.this is the temp.on idle(right) so when you put load to the cpu check how high it gets.just make sure your heatsink is dust free.and you could reapply new thermal paste

Okay, I'll look into doing that. How hot would it have to be to risk damaging other components?

70 is worry some, 80-90+ is dangerous.it should be in the mid 40 and lower

I really like CPUID hardware monitor. You can leave it running in the background for a while (several hours) and then see what are listed as the high/low temps for the cpu cores.

Yes, but keep in mind that it's the motherboard's temp. You should check the chipset's heatsink if it's still connected. And it will be hard to remove to apply thermal paste.

It is still connected, and the CPU seems to be running at only slightly higher than normal levels (based on what I've researched) and is idling pretty regularly at about 36C-37C degrees instead of the 31C-35C that the internet tells me it should. I'm guessing that this extra heat is a side effect from the motherboard idling warm. The fan is going at ~1k rpm when idle, so I'm not sure what to make of that.

That said, when stressing the system the motherboard's temperature doesn't seem at all affected. The CPU heats up to about 49C-50C, but from what I gather that's only a bit above normal as well.

Since these temperatures were high, so after tinkering I noticed a ton of air coming from the GPU port on the back of my case. I downloaded MSI Afterburner, and the thing is running at ~5.3k RPM idle. Which seems a TAD high for idle. Any thoughts on why it's going haywire? Do you think it's related to the motherboard's slightly elevated temperature?

Components heating other nearby components.

Sounds like you have very bad airflow in your pc case.


If you dropped lots of money on your video card and motherboard then at least do not go out and just buy a $45 pc case as that is just asking for problems.

I actually salvaged an old fan I had from an older machine, put it in, and the CPU is now running at normal levels, the GPU has stopped going crazy. The motherboard is still slightly warm, but the rest seems to be behaving as it should now. I'm going to continue monitering it since it certainly feels like a bandaid, but I'm feeling cautiously optimistic.

Well, it worked for a while but it now sounds like I'm next to an F-22 again. Did some more research, came across this thread:

https://forums.geforce.com/default/topic/666222/gtx-760-fan-problems/

In it, there are several people that describe exactly what I'm experiencing but there doesn't appear to be any resolution. I haven't been able to find another instance of this. It's idling at about 25C now but the fan started going full-bore at 5.3k rpm, and it doesn't increase at all when stressed. Afterburner said it was at 29%, which I doubt. If it's true, I'm curious to know how loud the thing can get!

Think it's just a faulty GPU since the cooling issue has been taken out of the equation?
