Here is my PC setup that I got from overclockers ~4-5 years ago.

  • "Titan Envy M DC" Intel Core i7 4790K @ 4.4GHz Overclocked Nvidia GeForce Gaming PC
  • MSI GeForce GTX 760 OC Gaming Edition 2048MB GDDR5 PCI-Express Graphics Card
  • Seagate Barracuda 2TB 7200RPM SATA 6Gb/s 64MB Cache - OEM (ST2000DM001) HDD
  • Samsung 250GB SSD 840 EVO SATA 6Gb/s Basic - (MZ-7TE250BW)
  • Kingston HyperX 8GB (2x4GB) PC3-19200C11 2400MHz Dual Channel Kit - Black/Red (HX24C11BRK2/8-OC)
  • Microsoft Windows 8.1 64-Bit DVD - OEM (WN7-00614)

My PC is fairly quiet when I start it up, but then when I do something like watch youtube or run a VM or play a game the fans quickly get noisy.

I used to think it was the graphics card. I even purchased a new beefier graphics card off a friend: so I now have a NVIDIA GeForce GTX 980 with 4GB memory.

But that did not have an effect on my fans. So I realised it must be the CPU causing the fan speed to ramp up.

But just watching youtube or simple things can cause it to get really noisy (it has always been like this - not a new thing). I am just tired of the noise. I did play around in the BIOS to change the fan speed profile - I set the PWM graph to as low as it would go until a certain temp and then it ramps up - I have played with a few setups - but always the same general outcome.

I am guessing my CPU just gets hot.

Is there any advice what to do here?

I am looking at getting more RAM - but I can't see that being the issue

EDIT: Just had a thought - would "under-clocking" the CPU help?! - I am that desperate!
 
@Minibiker I have not, that is a good point. I will setup msi afterburner - I used it to look at the fan and GPU temps, but I never did the same for the CPU (I thought it was only for GPU) - so I will start to do that and see what happen : )
 
As Minibiker says use something like HWMonitor / HWInfo64 to see what your CPU temps are doing, it may be possible that your pre-overclocked system was supplied with a BIOS fan profile that is too aggressive. Ideally you may be able to use a less aggressive profile to reduce fan speed and therefore noise. It might be worthwhile cleaning your cooler to remove any dust buildup to make sure it is performing at its best. If your CPU is constantly running mid 80c and upwards you could try repasting and reseating your cooler as it may not be making proper contact, do you know what cooler you have?
 
So I have been doing some testing using prime (to stress my CPUs) and HWMonitor to look at what is going on. I would like to paste the images here - but I can't see how that is done (needs a URL?).

When I run the tester (all cores == 100%) my CPU temps get up to ~100*C after 5-10 minutes, so I got a bit worried and stopped it.
Then I ran a lesser stress CPU cores all get to between 50-80%. My cores all seem to still jump up to 90-100*C - seems quite hot to me.

HWMonitor seems to be telling me the CPU fan is staying between 2250 and 2331 RPM this whole time (i.e. not changing). But I can hear the fans get really loud. These are probably the case fans (two on the top and one on the front).

As soon as I stop the test, the cores all drop instantly down to ~35-40*C - so would that imply that the thermal coupling is working well?

Also when I stop the stress test my fans only ramp down very slowly... I am not sure they ever go quiet again.

So now I am unsure if my CPU fan is doing anything (speed change-wise, although the fan speed does vary slightly) or HWMonitor is not working... just confused now...

My cooler (I took a picture): Is a corsair heat pump of some sort. The top two case-fans have a large heat-sink block attached below them and from there two thick cables go down into the corsair (labelled) heat cooler on top of the CPU. I am not sure how to identify the exact model.
 
Here is my images:

Temps / fan speed - Note the CPU fan speed min/max - does not appear to be changing - although I am starting to think the corsair fans (on the case) really are trying to do their job because I can hear them

oh, ok - that sounds like somthing I need to get on right away!

so thermal paste. Never done this before - but happy to give it a go!

Any advise on what Paste - there are loads even on this website! what about: https://www.overclockers.co.uk/noctua-nt-h2-thermal-paste-10g-th-002-nc.html?

No need to spend that much on the paste bud, something like this will be good enough

Total: £7.23 (includes shipping: £2.74)​

I consider checking the Pump on your cooler is working and also check the radiator over and give it a good clean aswell if needed
 
Thanks Minibiker - ordered it :)

How would you go about checking if the pump is not working? - from what I have (just) read by goolge'ing if the pump was not working my CPU (even at idle / bootup) would get really hot really quick and possibly shutdown due to over temp. Also I was reading the the fan speed RPM for these water cool pumps should be ~2200RPM which is what I was seeing (I don't understand that, but it matches what I see).

I am going to pull out all the fans and heatpump when my thermal paste arrives and see what happens :)

thanks very much for your support :)

Yeah now I've seen it's a AIO cooler I understand why your speeds are higher.... If it was the fans id have recommended changing the speeds in BIOS... However it could be a pump issue (may not be completely dead)
 
BTW when I dis-assembled my PC. The corsair water cooler heatsink had a really think layer of dust trapped between the two fans and the heat sink itself. Even my vacuum cleaner struggled to suck that off - it came off in think flakes!

I wander if that could be the reason the cooler was not working really well (i.e. stopping the air getting drawn through)?

I check also the thermal paste - that looked perfect (using my very in-experienced eye). There where some patches missing on the CPU, but they matched exactly the patches on the cooler pad - so I think the paste was put on well (and also very thin layer). It could still be the pump, but as I observed it did cool down really quickly when I stopped stressing the CPU, so I am thinking it just needed a good clean. Had I not taken it apart I would never have guessed that there would be dust between the fan and heat-sink :o

I'll probably end up re-build that PC (since I have nearly everything I need) and re-try it once I have my new PC up and running :)
 
One more thing - if I shacked the water cooler heat sink/CPU pad gently I can hear water sloshing about... does that mean there is an air gap? - or is that normal? - I assumed normal, but worth a check with you guys :)

Only skimmed thread so may have missed it. What case do you have and how is airflow setup in it? If case doesn't have good airflow and air is being pre-heated between intake and component by components' heated exhasut than things will run hot and loud regardless of hwo big the coolers on CPU and GPU are. Tell us what case you have and how case fans are setup and we might find a simple solution. Things like removing all PCIe back slot covers to increase rear vent area gives case better front to back airflow and lower air temp to both CPU and GPU coolers. Using good high pressure rated intake fans and blocking all openings in front not being used by intake fans so the air they are pushing into case has to move on through case to exhasut out the back, not leak back in front and go in circles. Have a tower cooler instead of stock downflow cooler helps too.

You might find basic guide to airflow and how to optimize case airflow in link below of interest.
