Hi All,

After experiencing a heavy lag and throttling in my MacBookPro mid-2015 model (A1398) recently, I had decided to check the fans for dust and thermal paste under heatsink.

Attaching my MBP specs:



And so, had successfully cleaned the dust and applied a new thermal paste - Cooler MasterGel Regular (https://www.coolermaster.com/catalog/coolers/thermal-grease/new-mastergel-regular/). I've even formatted the SSD and reinstalled BigSur to start afresh.

Although my MBP is working fine now with no throttling/lag, the overheating is still persistent and the fans seem to be maxed out.
Attaching a TGPro screenshot for the same.

Should i be worried about the fans constantly running at the max RPM and temp of 60-70°C always?

I'm thinking of reapplying a new thermal paste, like the Subzero Overclocking C14 paste

Would this be of any help?
Any other suggestions please?

    Assuming this is a legit post and not just a way to get your Amazon affiliate link in front of folks (that I've removed), the fans should not be running at full throttle all the time. CoolerMaster Gel Regular should be fine, so I suspect you have another issue.

    1) Stranger things have happened in the forums in the interest of getting an affiliate link in front of folks.
    2) Yet, there it was.
