Difference between Thermal Paste And Thermal Pads
As we all know that the surface of the CPU or a heat sink is not flat. So the uneven surface of both types of equipment give rise to the small gaps, and these small gaps are poor in thermal conductivity, as a result, the Gaming Computer gets heated off quickly.
To fill these gap we require a thermal conductive which delivers the entire heat coming out from the CPU to the heatsink and there comes the role of Thermal paste or Thermal pads for more info about thermal paste see here (https://glinkster.com/best-thermal-...)
But the real question here is which should you chose to avoid heating problems? Is it either thermal paste or thermal pads? So without wasting much time let's get to know what are the basic differences and when you should apply what?
What is the difference between thermal paste and thermal pads?
Thermal paste or thermal compound actually it has a lot of names. Thermal paste is a greasy conductive paste directly applied to the heatsink. It is most commonly used as the interface in between the non-conductive parts for the cooling purpose. A good thermal paste made with the best quality of thermal compound can work well for the system. To apply thermal paste, you have to very careful as you have can also sometimes drop it near to the main CPU. But this is not the only option to fill the holes in between the CPU and the heatsink, there is one more thing that you can use is Thermal Pads.
Thermal Pads
Thermal pads are easy to put as compare to thermal pastes. But they are not as effective as compare to the thermal paste. You will find some stock coolers come with thermal pads as it looks clean. If sometimes you have to replace the heatsink, then you have to remove the pad too. So remember whenever you remove the heatsink ot dismount it, always change the thermal pad.
Common Mistakes you have to avoid
There are some common mistakes that a lot of people make while applying the thermal paste or thermal pads.
1) Never use thermal paste and thermal pads together.
2) But you can use thermal paste on the top of the thermal pads to improve the efficiency.
3) Use of two or three pads altogether can kill the performance of the CPU.10 -
Ordered a Raspberry pi.
Excited to work on it.
Also ordered heat sink with it so as to make it 24/7
Till now I've thought to use as a cached DNS server+VPN client [and from it I'll share the incoming college WiFi to LAN (yes my college is finally getting WiFi for us in hostels)]+mopidy server with iris client
Give some more ideas.
Also, will the RPi be aple to work 24/7 without burning up if heat sink is installed?22 -
ZNC shenanigans yesterday...
So, yesterday in the midst a massive heat wave I went ahead, booze in hand, to install myself an IRC bouncer called ZNC. All goes well, it gets its own little container, VPN connection, own user, yada yada yada.. a nice configuration system-wise.
But then comes ZNC. Installed it a few times actually, and failed a fair few times too. Apparently Chrome and Firefox block port 6697 for ZNC's web interface outright. Firefox allows you to override it manually, Chrome flat out refuses to do anything with it. Thank you for this amazing level of protection Google. I didn't notice a thing. Thank you so much for treating me like a goddamn user. You know Google, it felt a lot like those plastic nightmares in electronics, ultrasonic welding, gluing shit in (oh that reminds me of the Nexus 6P, but let's not go there).. Google, you are amazing. Best billion dollar company I've ever seen. Anyway.
So I installed ZNC, moved the client to bouncer connection to port 8080 eventually, and it somewhat worked. Though apparently ZNC in its infinite wisdom does both web interface and IRC itself on the same port. How they do it, no idea. But somehow they do.
And now comes the good part.. configuration of this complete and utter piece of shit, ZNC. So I added my Freenode username, password, yada yada yada.. turns out that ZNC in its infinite wisdom puts the password on the stdout. Reminded me a lot about my ISP sending me my password via postal mail. You know, it's one thing that your application knows the plaintext password, but it's something else entirely to openly share that you do. If anything it tells them that something is seriously wrong but fuck! You don't put passwords on the goddamn stdout!
But it doesn't end there. The default configuration it did for Freenode was a server password. Now, you can usually use 3 ways to authenticate, each with their advantages and disadvantages. These are server password, SASL and NickServ. SASL is widely regarded to be the best option and if it's supported by the IRC server, that's what everyone should use. Server password and NickServ are pretty much fallback.
So, plaintext password, default server password instead of SASL, what else.. oh, yeah. ZNC would be a server, right. Something that runs pretty much forever, 24/7. So you'd probably expect there to be a systemd unit for it... Except, nope, there isn't. The ZNC project recommends that you launch it from the crontab. Let that sink in for a moment.. the fucking crontab. For initializing services. My whole life as a sysadmin was a lie. Cron is now an init system.
Fortunately that's about all I recall to be wrong with this thing. But there's a few things that I really want to tell any greenhorn developers out there... Always look at best practices. Never take shortcuts. The right way is going to be the best way 99% of the time. That way you don't have to go back and fix it. Do your app modularly so that a fix can be done quickly and easily. Store passwords securely and if you can't, let the user know and offer alternatives. Don't put it on the stdout. Always assume that your users will go with default options when in doubt. I love tweaking but defaults should always be sane ones.
One more thing that's mostly a jab. The ZNC software is hosted on a .in domain, which would.. quite honestly.. explain a lot. Is India becoming the next Chinese manufacturers for software? Except that in India the internet access is not restricted despite their civilization perhaps not being fully ready for it yet. India, develop and develop properly. It will take a while but you'll get there. But please don't put atrocities like this into the world. Lastly, I know it's hard and I've been there with my own distribution project too. Accept feedback. It's rough, but it is valuable. Listen to the people that criticize your project.9 -
I tried putting a heat sink on a couple of my PIs but have instead painted my keyboard with thermal paste.3

This is interesting from a troubleshooting point of view. I have a decent laptop I use to play Fallout 4. It was running just fine until recently. The game will spike GPU activity and crash. I found if I reduced settings and lower resolution it happens less often.
I kept searching and finally found someone saying it could be GPU thermal compound has worn out. So I looked how to change that on a laptop. The video I found it looked fairly easy.
I get into my laptop and I find all the screws for the heatsink/head pipe assembly. However there is a ton of thermal tape used everywhere holding it all down. I think if I am not careful I will break the heat sink. I did pull on the main part and it just didn't want to give.
Feeling a bit defeated as I put everything back together. I had gotten some decent thermal compound for this. So I fire up the game and it runs fine at the low settings. Then I raise all the settings to max with max resolution. This was crashing the game the last few days. It just runs and runs fine on those settings. GPU temps look normal (they did before, but I wanted to see). So, all I can think the act of lifting the heat sink a small amount may have reseated the thermal compound a bit. I am still going to price out a professional doing this, but I can play on max settings again. Maybe messing with screws on GPU and slightly moving the heat sink actually did something.
This confirms to me that something needs done about the thermal compound. The company I bought the laptop from offered custom thermal compound at time of purchase. So I am thinking they can do this for me. It will be cheaper to pay a couple hundred bucks to have a pro do this rather than pay $1800 for a new computer. This is only 2 1/2 years old. It has been a top performer up til now.6
