My AMD APU is getting too hot.

My A10 6800k cpu is getting really hot even when the PC is idle. I've recently put in a R7 260X. The APU isn't even using the graphics processor and is still hot. Its around 60-70 degrees when im browsing, watching movies etc, 50 degrees when idle and 90-110 degrees when I'm gaming even though I have 5 fans in my case at 100% load. If you were wondering, my case is a NZXT Phantom 410 with plenty of space for airflow. Is this how bad a stock cooler is? If it is the cooler's fault then I'm thinking of a custom heat sink. I have never ever installed a custom heatsink before, so can you guys suggest which CPU cooler is at a low price and user friendly? Im thinking of the NZXT Havik T40 or the Coolermaster Hyper 212 Evo.

I would remove the heatsink and reapply the thermal paste properly.

Where are you getting the temp measurement from? You should use the official software for the motherboard.

50 degrees at idle suggests maybe the heatsink isn't correctly installed(not tight), or maybe thermal paste isn't applied correctly.

I'm getting these temps from CPU-Z/ HW Monitor

The 212 Evo is always a good bet, but I'd first check that you have thermal paste correctly applied, those temperatures are far too high.

The current heatsink will probably remove by twist screws which you can undo by hand. Have a look at the underside of the heatsink and the surface of the CPU and make sure there's some thermal paste, whch looks like grey toothpaste. If you have any thermal paste, remove the existing layer and apply a fresh one to the CPU. Make sure you spread it evenly; use an old credit or business card if you can. Doing that may well solve the problem.

Aftermarket heatsinks usually require access to the underside of the motherboard and can be rather fiddly to install. Coolers like the 212 Evo are also very tall, so you need to make sure that your case has sufficient clearance.

The Hyper TX3 is your answer. But i have the same problem atm in my PC, and ive given my motherboard to the sevice centre as well as asked for a new heatsink. This because my stock cooler gave me very good performance for over 2 years before thermal throttling started.

I've changed the thermal paste twice with cooler master's high performance thermal paste. I've decided on getting the 212 Evo but my only concern is that I have a Asrock A88X itx board and the ram modules might completely not fit if I install it. My case is a NZXT Phantom 410 which has good airflow and enough space.

That's the other downside to aftermarket CPU coolers, they usually block the first DIMM slot, particularly on an M-ITX board. If you have to use it, then you can buy low-profile RAM if height is the issue.
