Hey, it is my first time building a computer and I am having some kind of an issue.

I'll list my part just in case it is related ( I am not too sure so sorry in advance)

Mobo: MSI 970A-G43 AM3+ AMD 970 + SB950 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
CPU: AMD fx-8320
Graphic card ( dunno if it affects it): Nvidia 660 GTX Ti

I got 1 x ENERMAX ETS-T40-W White 120mm Cluster CPU Cooler with Cluster APS PWM Fan running at 2000 RPM or so ( i think , its on the 800-2000 RPM option)

However, when I started my computer, it starts automatically at around 45 celsius and goes up to 54-55 in 15 min and settles there. I applied thermal paste too between the heat sink and the cpu. (the size of a quarter or something?)

Any insight on what the problem might be?

If you are certain about the application of your thermal paste then there are other things you need to look at and some more info you need to give us.

What are you using to monitor temp?
What are your fan speeds?
Do you have the cpu cooler fan plugged into the CPU fan connection on the Mobo?

Your bios temp is the most accurate. However, I believe it gives you socket temp and not core temp.

If you are using speedfan to monitor temp it also gives socket temp and not CPU temp.

Download HWmonitor and run it. You will see a sub category with your chips name at the header. Under your chip ID you should see something that says "package temp." This is the actual temp that your CPU core is at taken from a thermistor near the core. This is...

I just took off the heatsink and cleaned off the thermal paste, applied literally a rice size shape and it still goes up to 50 celsius ( started at 45 and went up slower) but still goes as high. I bought the thermal paste separately, is it possible that it might just suck ( the paste that is)

Silver 5. Went to an electronic store told me it was the best one they had :/ 10$ a pop. I changed it to a pea size ( I used a card to spread it and realized it was bad?) So I changed to a pea size and its staying at 48 celsius?

At this point, I suggest checking the BIOS to see if you're at 1.35v for the vCore. If it's any higher, probably lower that and see if it helps. Maybe someone else coudl probably give you a better answer, I can't really think of anything off the top of my head right now.

I tested the fan with an ice pack ( I mean cold is still "heat" right?). It got from 25 degrees to -5 degrees but when I install it on the cpu which is at 50 degrees, then I don't feel anything, I can feel some "warmth" but no where close to 50 degrees

Download HWmonitor and run it. You will see a sub category with your chips name at the header. Under your chip ID you should see something that says "package temp." This is the actual temp that your CPU core is at taken from a thermistor near the core. This is what you need to pay attention to.

If you still get high temps:
remove the side panel of your PC and see if there is any change in temp. If it drops you have an air flow problem in your case. If not then your air flow is not the issue.

Next(or maybe first). you need to make sure that your cpu cooler is rated for the TPD (max power ourput) of your chip. For a 125W chip you need a cooler that can handle 125W of heat. In the manual or website it should tell you max CPU wattage the cooler is meant to work with.

If all of these things check out then RMA the chip. The chip housing may not be thermally bonded to the cores to dissipate heat properly

Well AS5 does have a settling period of 200 hours or so until optimal temps will be seen. With that said 50c is still pretty high idle especially for having an aftermarket cooler. My suggestions would be first to use the spread method with a rice grain sized amount of AS5 applied to the cooler base, not the IHS of the CPU. The reason for this is that you have a heat-pipe design cooler and inherently there will be small gaps between the heat pipes and base of the cooler. The concept is to fill these with thermal paste and eliminate any air gaps. The idea for thermal paste is to have as thin as possible of a uniform complete layer across the thermal surface. The grooves and irregularities the thermal paste is filling are only thousandths of inches and not much paste at all is needed, using more than needed actually reduces thermal efficiency. Also I would look into your bios and make sure your vcore is not on default as the default setting will often pump a large amount of un necessary voltage in to the core, even at low power states.
