Imagine being in a hot room with a ceiling fan: it's much more comfortable when the ceiling fan is blowing air directly onto you, even if the air near the ceiling is warmer than the air near the ground due to convection.

I think I did it wrong, now I'm hitting low 80s. Maybe I used too little paste now? I don't know. It's like I've never built a computer before.  On the upside the temp comes right back down as soon as I kill Prime95...can't be too bad in that case I guess

It might just be the break in period for the paste, it can take a little while for the temps to normalize right after applying new paste.

I just wanted to add from the earlier convo that with the typical monitor you tear and stutter constantly. It's just fast enough, for the most part, that its hard to point out and say "that's tearing"... until its bad enough. That's why (I assume) with g-sync or freesync you can have two identical framerates and feel the one with the variable refresh looks so much smoother, even if the normal monitor doesn't actually look like its tearing. For example this is an average of 89 fps, and a smooth looking 89 fps at that.  Its probably tearing almost every frame, even if just a little.

Ziploc posted:How old is too old? Second opinion here, Arctic Silver is crap, even if you buy a fresh tube it is probably New Old Stock that has been sitting for a decade. I put a fresh coat of it on a delidded 4770k and had very bad temps, did it over again precisely and got the same bad temps, finally bought a syringe of Notcua NT-H1 for 5 bucks and it dropped me about 20c doing the same application method a 3rd time. Between that and the NT-H1 tube having enough for like 20 applications, and being non-conductive while the AS5 conducts, I'd say save yourself the frustration and get the good stuff. Noctua also makes some of the best coolers and they toss in a tube of NT-H1 with pretty much all of them.

The benchmarks puts NT-H1 with the best of them and it's cheap. Definitely one of the easiest pastes to work worth, used it on dozens of machines and never had to reapply it once unlike AS5 and others

td4guy posted:On which side of the heatsink do you have your CPU fan installed? It's supposed to push air onto the heatsink, not pull air through it. Pushing through. I managed to mount both of my case fans backwards. I'm still hitting 80 with Prime95 but that is a real outlier so I'm going to run it a bit and see how it feels.

Just bought a GTX 970 to replace a creaking 460. I've noticed straight off the bat that Far Cry4 now runs lovely which is what I wanted really. I did give Rise of the Triad a go and it kind of jerked a bit while playing and eventually crashed. I know the GTX970 is a very decent card so I wasnt expecting that really. Some games have also stuttered now and then. I'm running with a i5-2500k (not overclocked), 8GB of RAM and everything is on an SSD so I'm quite sure I've not gimped myself too much. I'd like to know, if anyone has any tips, what would be the best steps to make sure everything is running top of the line. Should I have clean wiped the OS rather than removed all drivers, are there any utilities I should run to ensure things are optimum, are there any nvidia control panel configurations I should have as a must? I appreciate this is fairly open ended just want to hear other people's tips if they have any. Is it time to perhaps upgrade the processor too?

I guess I should have said there's very little meaningful difference between pastes that aren't cheap poo poo, but eh. The CPU graph was what I expected but I didn't expect differences for GPUs. I guess there's something significantly different about the characteristics of how GPUs heat up. But people who put aftermarket coolers on their GPUs are a much smaller group than the people who put aftermarket coolers on their CPUs so the results that are specific to GPUs are of limited use.

I'd never heard about that Coollaboratory stuff until I saw these benchmarks and it looks kind of tempting for when I next change my CPU/cooler. Its consistently 10% better than the 2nd best products, and considering we're probably all overclocking and chasing temps to get a solid overclock, 10% can be a nice drop. The reviews say its kind of tough to apply though. Even if you aren't replacing GPU coolers, just popping the original cooler off and putting this stuff on would make a difference as per the benchmarks. I don't know what MSI/Asus/EVGA's OEM paste is like but if its drops like in those charts, thats the sort of drops that will let you turn your 970 into a 980 in terms of overclock performance, and dropping £7 on thermal paste for effectively a £100 hardware upgrade sounds pretty decent.

On top of the lid there are much easier pastes to use which are within the margin of error.

I guess I should have said there's very little meaningful difference between pastes that aren't cheap poo poo, but eh. I push GPU repasting all the time. Its a huge difference, sometimes ridiculous. Its due to surface area of the die. Lowest difference I've seen is around 7 degrees drop. Best has been 20 degrees. And those were cards of the same chipset, different brands. It's also very easy to do.

OK, no...I'm hitting 100C now. I'm pretty sure that now there's too little paste. Couldn't get it to spread right. Also LLC only has "normal", "high, and "turbo"...no off on my board.  e: I am tempted by that Coollaboratory pad. No fussing with paste there!

Pre-spreading the thermal paste misses the point of the paste. The paste isn't there to coat the CPU die, it's there to fill in gaps between the CPU lid and the heatsink. If you pre-spread it you're going to be putting more paste than is needed in some places and too little in others. Unlike when you put one drop in the middle, pre-spread thermal paste will seal in air bubbles. When you put the paste in the middle and rely on the heatsink to force it away from the center the paste is all displacing air in the same direction (away from the center) so no air gets trapped. Maybe it doesn't result in a huge, noticeable difference in temperatures most of the time, but there's no reason to pre-spread thermal paste when it takes more effort than just putting some in the middle and it can only make the contact worse, not better. If nothing you can do results in good temperatures a possibility is that your particular CPU just isn't making good contact with its lid. Delidding is not something you should be doing if you're not an expert so you might just have to live with the temps you have.

I don't really see how flattening the paste out by hand helps any if the cooler mounting pressure is any good at all. (and if it isn't good, spreading the paste out by hand isn't going to help).

I always worry that I don't put enough on to fill the contact surface, but that's probably not a reasonable concern.

Subjunctive posted:I always worry that I don't put enough on to fill the contact surface, but that's probably not a reasonable concern. The actual CPU under the lid is a good bit smaller than the lid, so as long as you do the standard pea sized dollop of paste in the center you will get plenty of paste where it needs to be.
