What i did with mine is to remove the back aluminum in order for the hot air to escape easier,cant test it yet tho cause my CPU is still not here.....I assume it will make a difference but how much not sure yet. Personally i find 85c too hot i would not want my cpu to run hotter than 75 at worst.Thankfully you can do that from the bios.I would advice not to touch timings cause it will produce even more heat inside the case with minimal returns...Just use the faster profile and you will be fine.Do you have an external GPU?
