Problems with PC Cooling.. even after MasterCooler Hyper TX3 EVO

haljordan18 · Dec 22, 2017

Hey guys, I have a small problem I hope you can help me.
A couple of days ago I finally replaced my old AMD "Stock" cooler for a Master Cooler Hyper TX3 EVO.
I decided to replace the cooler because of the high temperatures (Around 50º idle, and 75-80º when i was running games such as battlefield 1 or GOW4, etc) and of course the old cooler was very noisy..
However now, the improvement was not as i expected. At Idle i get around 45º Celsius, and during Gaming I get 70 or 75º Celsius.
My PC specs are:
-CPU: AMD Phenom 2 X4 965 Black Edition @3.4GHz (Im not overclocking the CPU)
-RAM: 8GB OCZ Reaper DDR3 PC12800
-Video Card: Sapphire Radeon RX460 Nitro 4GB
-120 SSD Sandisk.
I used the thermal paste that came with the Hyper TX3 EVO.
If it is helpful, I attach a picture showing the location of the fans on the PC.

Thanks a lot in advance for your kind help.
PS. (My power suppy is located on the top left corner of the picture im attaching to this threat)

What CPU? Is it OC'd?

Do temps drop when you remove the side panel?

Mark RM :

Yes! around 5 degrees, not more than that.
CPU and OC are on the description above

I used to have the same cooler and CPU on a K9A2 Platinum. The heatsink itself has gaps between the heat pipes. I had similar temps, not really much you can do.That being said, it performed on par without throttling or overheating.

A cooler at idle should be 10-15c. over ambient.

Did you use too much paste?
If so, it acts as an insulator.
A rice sized drop is sufficient.
Pushpin mounts are difficult to do well.
They go on unevenly unless you push down on diagonal pins at the same time.

Any cooler needs a source of fresh air to do its job.
I think a single front intake fan is insufficient for a hot cpu and a hot graphics card.

Your test of removing the side covers indicates that more intake would help.
You can replace the front fan with one of higher rpm and airflow.
But, at the price of more noise.

Then, the TX3 with a puny 92mm fan is not very efficient.
If you have 160mm available for a cooler, spend $35 on a tower type cooler with a 120mm fan.
One of the best is the scythe kotetsu.

The hyper212 is popular, but hard to mount, and not as efficient.

If you have only 145mm available, the cryorig H7 is excellent.

Lastly, you might try a slot fan under the graphics card to draw off some of the heat from the graphics card.

AMD processors do not have the heat tolerance of Intel, so you need to pay attention to this.
Likely at 70c. your cpu is throttling and losing performance.

Sorry you did list all that - I had a total brain fart.

I basically agree with everything geofelt has said. Considering the setup as it stands, the cooling is about where it should be.

His recommendations for positive change are all good ones.

Thanks a lot man, your explanation was deep and very clear. I will try out everything you suggested.
