I recently started playing Overwatch and wanted to run it at 144Hz with 1080p resolution. However, at stock clock speeds (3.5GHz) on my CPU, frame rates dropped significantly between 90 and 120. To address this, I experimented with overclocking by increasing voltage and multiplier according to online guides. I also upgraded my CPU cooler and installed a liquid cooling AIO unit for the GPU using an NZXT mounting bracket.

Now, I can maintain a consistent 150fps in-game while setting the in-game fps-limiter to 144fps (ranging from 150-220 uncapped). There are no frame drops, and I don’t think thermal throttling is occurring. Still, I’m concerned about the temperatures I observe during high load.

System details:
- FX-8320 OC'd to 4.5 GHz (cooled with H100i GTX)
- M5A99FX PRO R2.0
- 8GB 2133 MHz RAM
- Gigabyte r9 280x (cooled with a thermaltake water performer 2.0 via NZXT G10 bracket)
- Corsair CX750 80+ Bronze
- Ambient temperature: 30°C

I’ve adjusted the waterblocks on both CPU and GPU, used higher-grade thermal paste (Arctic Silver 5), added an extra intake fan (removed ODD), and even mounted the stock AMD heatsink fan directly onto the VRM heatsink to improve cooling. No noticeable temperature differences were recorded by software.

These adjustments seem normal for the airflow I have in the case, especially considering both the CPU and GPU are water-cooled with pumps running at full capacity via a Molex adapter.

The maximum temperatures (77C) seem excessive if they occur more than occasionally. Consider using AOD and monitor thermal margin instead. Sometimes AMD CPUs display inconsistent readings with third-party software.
