Hello, I recently changed my old motherboard to a new one and in order to do that, I switched all my components across. It's an Intel i5-4590 with a stock heat sink. Ever since rebooting into the new motherboard, I could hear my fan being louder and I checked the temperatures and they're sitting on 40 degrees+ on idle and about 70 while playing CSGO. I noticed the sound because I used to never be able to hear my computer. The fan is too loud that it's even distracting while playing cs, hard to hear footsteps. Goes over 2000 rpm.

I removed my cpu heatsink, cleaned the thermal paste with Servisol IPA video 40 and then used coolermaster thermal paste on it. I put a small dot in the middle as I've watched on a ton of videos on youtube. I thought it was due to me applying it wrong and tried redoing it about three times already with varying amounts of thermal paste. I turned over the motherboard and could see the other ends of the heatsink sticking out properly but I did have trouble putting it in the first time as one of the tabs was insistent on not going in.

I could buy a new heatsink, it's not an issue but I think that it would be better for me to diagnose the issue before I do that and make sure it's the fault of my heatsink as my computer was working quite and fast before switching the motherboards.

Thanks a million in advance :)

the temps are pretty much what I'd expect from a stock cooler

the difference might be the fan profile in the bios of the new motherboard

do you know what temps you were running at on the previous mobo, or had you not checked because the fan wasn't as noisy?

It's a GA-H81M-S1, I switched from an MSI-b85m-e45. And yes, that's what I was thinking as well. I could switch the cooler but then I might not see another issue at hand here.

different bios might be handling the cpu at different settings

check your bios version first. according to the spec sheet for that mobo, intel 4th gen cpus were supported from bios version F5 onwards. So update to latest version if you haven't already

after that, check what stock voltage the bios is applying to the CPU

It did say F1 so I do need to update the BIOS, will do that now! :) And I do not know what the stock voltage you're referring to is but I was able to find the following information from my BIOS>
https://scontent-amt2-1.xx.fbcdn.net/v/t1.0-9/21032556_1135106553286139_3928861256632301713_n.jpg?oh=5272c61e2aef9195328f92eaf7b79922&oe=5A22C441

It does say that CPU vcore is 1.050V and CPU Vrin voltage is 1.8. Thank you so much for helping me with this! :)

It isn't very loud as I turn the computer on. As it boots up, my idle temperatures are at around 35 degrees. As soon as I open chrome and start browsing the internet, it goes to about 40-45. Playing a video, it goes upto 55. Playing cs for about an hour made it hit 70. I can really hear it being loud while playing CS. I can hear a change in the fan sound when it hits the 55+s, I never remember hearing that much sound from my CPU before.

That should be it then, and no, I didn't bother checking as I didn't have any issues with the fan speed or my CPU. I had only checked it a year or so ago when I installed new case fans and my cpu was running at 30 degrees on idle back then. I have not stress tested it at all before yesterday. I'll buy a new heatsink. Thank you very much.

I've tried small dot, a bigger dot and the vertical line method :(

depending on your bios, you might be able to tweak the fan profile/curve to be less agressive

if it lets you, don't lower it too much to start with
