The FX journey into under-volting an 8 core CPU


I have had my FX-8320 for a little over a month, but I couldn't help but notice how hot in general these things run. Even though I am using the stock cooler, and the chip has never surpassed the 61c core temp danger zone, it has came close a few times. I couldn't for the life of me believe that the stock cooler for this chip was "that bad".

I just thought these chips ran a little on the hotside in general, and as long as you don't exceed 61c on the core and 70c on the socket temp, then everything was ok. That is true, but I had an idea to try a little experiment. I thought, lets see what the stock voltage is on these things, and see if we can lower that in any significant way and see what we get.

According to CPU World, the FX 8320 has the following Boosted Pstates (Voltage at Turbo Core Clocks)

#1: 4000 MHz, 1.425V
#2: 3700 MHz, 1.4125V

The Stock Voltage at 3.5 GHz is anywhere between 1.3375 to 1.3875v depending on the motherboard and manufacturer. On my Biostar TA 970 v5  the default Vcore was set at 1.3375 volts.

Now with this information in mind, I set out on my under-volting journey.

Positive vs Negative Pressure PC Case Cooling


Picture of Computer Case

Positive VS Negative pressure.....this is a debate that has raged among PC system builders for a very long time, and a debate not easily answered. Today, I will "Attempt" to answer this question. Attempt being the key word here.

Before we dive into this discussion, I just want to point out that positive and negative pressure is a term that gets thrown around a lot in discussions,  but most computer cases you find today on the market for gamers have so many holes, vents, and meshes on then that positive or negative pressure is not the most accurate way to describe them.

When speaking of Positive Pressure and Negative Pressure,  I am referring to the following:
