and i noticed that it has a pre-applied ARCTIC MX-4 thermal compound.
after removing the old thermal paste from my cpu, should i apply a new one?

You sir, have a broken sarcasm detector. That is definitely not sarcasm. You should sandwich as much thermal paste as you can between all major components of the your box, in fact an alternative and cheaper liquid cooler option would be to submerge your entire rig under about 3L-5L of thermal paste. | ||

Running without paste isn't too much of an issue if you have smooth plates, the rougher the surface, the more the paste helps, but the difference isn't that great, as the paste sucks for conducting in the first place. | ||

And it is definitely good to have one person giving serious advice in case the OP doesn't get the jokes. On an unrelated note, I bet you could get mechanical robot fish to work in that tank. | ||

If you have your own paste, I personally would remove the pre applied. However the pre-applied will be perfectly fine. The actual method varies for a dual core or quad core but I have always just done a dime sized amount on the cpu. I use an aftermarket heatsink which has gaps on the base of it, so before I put in on my CPU, I use an old bank card to smooth a thin (almost see through) layer of paste on that first to fill in the large gaps. The idea is when you clamp your heatsink it should spread out, so if you put anymore than a dime (some say grain of rice) it might spill out, which you definitely do not want. Thermal paste can ruin a mobo if it shorts it. | ||

Because even the best paste generally doesn't conduct as well as whatever metal your components are made of, you want to use as little as possible to completely cover the surface. Put a dab (a pea-sized drop is usually more than enough) on your CPU and spread it out as thinly as possible with a credit card, taking care not to let any spill over the edges. It should be visible but translucent when you're done: if you can't see through it, you used way too much. Do NOT put a bit on and then just smoosh the parts together. You won't get an even application, and you're more likely to run the risk of it spilling out the sides. The key to proper application is a very thin but very even coat that covers the whole CPU. If you do it right, nothing will spill out when you attach the heat sink because there isn't enough there to get smooshed out from between them. | ||

and corpuscle's got the right advice. ^^ Personally when i've gotten pre-applied sinks, I find that there's usually far too much paste there, so I remove it and do my own coat. | ||

For reference, my temps are usually around 45 for the cpu, 30 for the mobo, and 70 on the graphics card. | ||

For reference, my temps are usually around 45 for the cpu, 30 for the mobo, and 70 on the graphics card. Those temps are fine. If you spend the money (or have some lying around) to replace it with new thermal paste you will probably see temps go down a few degrees but that really does not matter at that temperature. IMO spend your time/money somewhere else because it will not have an actual effect on performance. | ||

What is everyone elses experience? Doing the dot technique works, but it's really still not ideal for a few reasons. First off, it's really hard to get the exact amount right: as the video shows, making a dot and then smooshing the contacts together gets you a circle, and processors are square, not circular. There's no way to cover the entire surface with paste with that method unless you use too much, and it's hard to get even an ideal circle (which would have the same diameter as the processor's width). If you're leaving some portion of the CPU paste-free, you're not getting as much out of the paste as possible. Second, it's harder to tell if you've used the right amount or not. If you've done it a trillion times and know the exact amount you need, sure, you can probably get it right, but most people apply thermal paste once every five years, so it's not exactly something you're going to get a lot of practice with. You can double-check if you have the right amount by disconnecting the heatsink, but... why? Just spread it out ahead of time. It's really not that hard. I realize that there's a lot of "right" ways to do it, and it's really not something that matters all that much anyway, but from poking around on google, there seems to be a lot of people advocating the "make a dot and smoosh it" method, which is just absurd, because it's clearly less effective and only marginally easier. Three of the product manuals I have that talk about applying thermal paste tell you to spread it out thinly and evenly with a credit card, but the internet seems to disagree... | ||

Most of the time preapplied paste is not enough, so as mentioned above, its better to remove and reapply. The way to remove it is with rubbing alcohol and apply a new fresh paste. Hope it helps! Haven't they established that this is a terrible idea? I'm probably just falling victim to a troll, poor me. | ||

If you're leaving some portion of the CPU paste-free, you're not getting as much out of the paste as possible. You don't really need to cover the entire heatspreader. The actual CPU only takes up a fairly small (15%-20%) of the surface of the entire thing and it's located directly in the middle. While the heatspreader does spread out the heat somewhat over the entire area, the majority of the heat is still transferred via the central area, so optimal spread over thermal paste in that area is far more important than in the edge regions. Which is exactly what you achieve with the rice-grain-technique. | ||
