So this isn't a problem - I'm just curious. I was replacing the thermal paste of my ThinkPad because summer is here and this thing was howling like a beast. I used some Arctic MX-4. Everything went alright. Not much of a change in temps but rather a huge change in acoustics. I actually thought I forgot to plug in the CPU fan because it just wasn't working at all. But in the process of replacing the thermal paste, I noticed something I've never seen before. Not because it is rare, but because this was actually the first time I replaced the thermal paste of a U-series chip. It had two dyes in it! Like this: https://imgur.com/a/aGchAPI To my surprise, only one of them had paste in it - the large one. Now at first I thought the small one was just the integrated GPU, so I didn't think it through and applied thermal paste into it too. Now I'm feeling worried about doing that. There must've been a reason it had no thermal paste in it. And that's why I thought I'd ask here... So to top it off, my three questions are: 1) what was the additional smaller dye for? 2) why didn't it have any thermal paste in it? 3) did I screw up by applying some paste on it? Thanks in advance

Hi LTT forum, this is the weirdest issue I've ever come across when using a top-class website like YouTube. I don't really mind it that much, it's easily fixable, I'm just really curious to know what is going on. So here's what happens. I'm on YouTube, and screen goes black when I go full-screen. But this only happens if 1) the video is on 720p. There's no issue whatsoever when watching in 1080p or 480p. Only happens if the video is on 720p. Now I don't use 720p that often but some videos go only up to 720p in some cases. That's the only case when I use it. And also, 2) my laptop HAS to be on battery. If I plug it in, the problem does not occur any longer. Now I usually use my laptop at home, so it's easy to just plug it in when I'm watching a 720p video. What REALLY bothers me, is how puzzling this whole thing is. How and why exactly at 720p? Why when on full-screen? Why only on battery? It just doesn't make sense... here's a couple more clues: - the screen goes black only after the media buttons bar (pause/play, next, volume etc..) have disappeared, which happens after 3-4 seconds of not moving your mouse - if you do move your mouse while the screen has gone black, you can briefly see the mouse cursor moving for a moment, before disappearing again, and then the media buttons bar shows up again making everything normal. - my screen goes to 50Hz refresh rate when on battery, to save battery. I have no idea if that has anything to do with this. I'm just incredibly interested to know what's going on and, if there's a fix, apply it. I hope you guys can solve this mystery. Thanks! EDIT: I'm on a ThinkPad T460s using a touch 1080p display panel.

I understand. So it really is better than a standard USB-bluetooth adapter. Yes I do have one free USB2 header on my mobo, so it's perfect. Thanks a lot guys, I'll give it a shot and post updates about the performance. I've got high expectations for this one

Thanks for the reply. That might be the reason why these converters come with 4 pin to 9 pin USB cable to connect with the motherboard USB. Does that mean that the whole thing is just a fancy PCI-e powered USB-to-bluetooth adapter?

Hi LTT forum, I'd like to have excellent Bluetooth on my PC so that I can play games using my Dualshock 4 wirelessly. Firstly, I bought a cheap $2 USB Bluetooth adapter which works okay with a mouse, but sucks when using a DS4. I'm getting 100ms latency while close to the adapter, and over a second of latency when playing from my couch 3 meters away. Now I thought I'd purchase an ASUS BT-400, but the cheapest I can find on eBay (the only website shipping to my country) is $49.5, so no. I purchased a macOS compatible Broadcom network card to swap the Intel one in my laptop, which left me with a spare Intel AC 8260, which handles Bluetooth exceptionally well on my ThinkPad. I was thinking maybe I could buy one of these M.2 network card to PCI-e converters to use with my AC 8260 on my PC so that I could have not only Wi-Fi but great bluetooth for gaming. But I'm unsure because I've never used one of these converters, and I don't know how efficient they are. So that's why I thought I'd ask here before I buy. Also, if there are better alternatives, please let me know. I'd also like to hear about your experience using bluetooth controllers to play games on your PC :) Any help is appreciated. Thanks
