Don’t Use Liquid Metal on Aluminum
A few weeks back I posted an article about liquid metal cooling in notebooks. It can be used as a substitute for standard thermal compound in some situations, but not all. Member Danishblunt started a discussion on what happens when you use liquid metal on an aluminum heatsink, and the results aren’t pretty. (Hit up that link to watch the video.) Bottom line: Don’t even think about trying liquid metal if you have an aluminum heatsink; it’s copper or bust!
HP’s New 2018 Pavilion Gaming Notebooks
I took note when HP announced its new Pavilion Gaming brand in April this year, promising to bring powerful performance to mainstream gamers. The HP Pavilion Gaming Laptop 15 is available now and starts at just $699. It’s a direct competitor to Dell’s G-series gaming notebooks.
This 15.6-incher offers a 1080p display with a 144Hz refresh rate for fast-paced gaming, or a 4K display for finer details. It’s powered by eighth-generation Intel Core processors and Nvidia or AMD dedicated graphics solutions. The keyboard backlighting is available in three different colors: Acid Green, Ghost White, and Ultra Violet.
- 6-inch display, anti-glare, with a 1080p or a 4K screen resolution
- Intel Core i5-8300H quad-core or Core i7-8750H six-core processors
- AMD Radeon RX 560 (2GB), Nvidia GeForce GTX 1050 (2GB), GTX 1050 Ti (4GB), or GTX 1060 (3GB) graphics options
- Up to 16GB of DDR4-2666 memory
- One 2.5-inch bay and one M.2 slot for storage
- 3-cell 52.5 watt-hour or 4-cell 70 watt-hour battery options
- Available IR webcam for facial recognition
- Bang & Olufsen dual speakers
- Dimensions (WxDxH): 14.4 x 10.1 x 1 inches
- Weight: 4.78 pounds
Forum member Uachaic states it has a nice-looking screen and loud speakers, and reasonable overall quality.
Troubleshooting High Notebook CPU Temperatures
Every now and then something inexplicable happens, which appears to be the case with forum member Prototime’s MSI notebook. The CPU temperatures appeared to have increased drastically over the past couple of weeks, seemingly without reason. Our forum members suggested the following troubleshooting tips:
- Apply new thermal paste. A poor thermal paste application can result in uneven temperatures.
- Undervolting the CPU using Intel’s XTU utility. This reduces the processor’s power consumption.
- Look for software taking up resources and forcing the notebook to work harder than it should, such as malware.
The above suggestions were tried without full success, although the temperatures were reduced slightly. It’s been suggested that perhaps the CPU temperature sensor is faulty. If you think you can crack the case, chime in here.
Faulty HDR Monitors
High Dynamic Range (HDR) on PC monitors and TVs is a new feature that’s being touted to improve image quality. It’s bringing its share of troubles to the early adopters in the PC world, especially gamers using high refresh rate monitors and 4K displays.
Forum member hmscott posted a discussion thread on the topic, pointing out how some HDR monitors sold by Acer and Asus are using color compression to achieve HDR with a 120Hz or 144Hz refresh rate. It looks like the problem right now is that even DisplayPort 1.4 doesn’t have enough bandwidth to handle HDR at high resolutions and refresh rates. It’s a problem right now, but shouldn’t be when new GPUs are released supporting HDMI 2.1.
