    I usually just clean the CPU heatsink fins, Fans, and such, never touched Thermal paste on any of my CPUs over the years, and never had system over heat i don't think, then again they could've, but i don't overclock, so perhaps i didn't notice lol

    It is very normal that all components get a bit hotter with age. Not much, but enough so that the compounding effect is what you see on the CPU temps.


    As others has mentioned, clean ALL dust from the computer, including the PSU. Also make sure you have some sort of gloves, so you don't apply grease from your fingers when touching components. That will make the dust stick even faster. A thin layer of dust on all components can have a surprisingly high impact on temps.


    I don't own any Corsair AiO- pumps so I have to ask. Do you have any means of measuring the water-pump RPM and flow? Is it up to specs? It could be that the pump performance is degrading a bit.


    45 or 55 degrees temps are nothing to worry about.

    HW monitor is often wrong reading temps. For older AMD based systems AMD Overdrive AMD Overdrive Utility 4.3.1.0698 Download - TechSpot is much more accurate.

    Leave the heat sink and thermal paste alone. It sounds to me that you have air flow restrictions, make sure the fans and inlet screens are clean and nothing inside the PC (cooling hoses, wiring harnesses) is restricting airflow.
    BTW the CPU block and rad are supposed to feel hot if the're doing there job.
    There is no airflow restriction. All the fans are working as they should, although they are probably dusty so I'll get some cleaning equipment to blow away the dust.

    I have no idea how to check the flow but the RPM of the rad-fan is roughly 1200 RPM.

    Hi,
    Thermal paste is nearly the easiest item to do
    Some talking like it's a major no-no lol :)

    It's a good thing I did clean it out because there was a big enough circular space with a dangerously little amount of thermal paste on the center of the CPU. I cleaned my system out as much as I could, used my CPU cleaning kit to clean off the old thermal paste and apply fresh new paste using Arctic Silver 5 and reinstalled the CPU and liquid cooler. My motherboard thought I had installed a new CPU but of course that's to be expected.

    Overclocking of my CPU has been reapplied and is now back at 3.8GHz. I would love to overclock my CPU back to a stable 4.4GHz as I had once done before but I don't remember what overclocking settings to use so 3.8GHz is good enough until I figure it out. According to HWINFO my voltages and temperatures of my NB/SB/CPU and GPU are looking good!

    The question here is, when is the ideal time to do this?

    What are your thoughts?
    My answer was going to be when the computer is shutdown......

    Shutdown because something melted ?

    What is dangerously little? Only thing the paste have to do is fill the cracks on both CPU and cooling block. We are talking fractions of millimeters here. We are not building a brick house out of CPUs and blocks, where the amount of fill in between requires almost an inch of stuff.

    If your paste is all over the CPU, there was too much paste. :)

    Hot spot is right in the middle of processor 10 - 20 mm square where processor core is.

    Left is processor and right is it's cover.
