  1. Thanks!

  2. Hey Kitguru did you run into any issues with main board thermal sensor during your testing or rather do you know what the main board thermal sensor is actually measuring because I’m running the main board with a r5 1600 at 4ghz 1.4v and Main board sensor is reporting 98°C after 15min of prime95. Which seems stupidly hot given that I’ve got 4Nidec Servo GentleTyphoon 120 mm 2150 RPM fan’s in the case. I kinda just wanna know first of all if that thing is the VRM sensor or “chipset” because which ever one it is guess I’ll add to the custom loop. Because 98°C during stress test just doesn’t sit well with me.

  3. “MSI’s RGB lighting control tool is sub-par on the Tomahawk SKU as MSI is clearly trying to push RGB aficionados towards ‘Gaming’ branded models.”

    What kills me about this is that you can only “push me” into a higher priced model IF YOU TELL ME about the shortcomings of the cheaper model! Granted, this many fan headers and an LED header on a $90 board were all a major win but come on. If MSI made it clear I’d only have 7 colors I would have happily sprung the extra $25 for a better featured board. Instead, they called it “RBG” and make mentions of Mystic Light and its16.8 million colors on the product page. Not only misleading, but they fouled up the whole strategy of driving me to a more expensive board.

    I know they fixed a few of the Tomahawk’s issues with the PLUS model, which has no legacy PCI slots and more colors than just red for the on-board LEDs. I wonder if they made the LED header full RGB, too. Hard to find an answer on this.
