How important is CPU performance for 3d vision?

Metaloholic, these tests are in a GPU bound scenario mate; that's why you are not seeing much of a difference when you change CPUs.

but the firestrike ultra was done in 2D. and when comparing the results were valid. i know benchmark is a benchmark but im just saying. the difference in 5 year era is almoust laughable ( don´t know how that should be writen)

Gentleman! Bob, Rage, I have it. I found a great post from a guy that has tested various scenarios for the data we needed: I'm going to order two high static pressure fans to mount below my rad up top for push/pull. I think I might test it without the rad sandwich first to see how loud it is. Clearly though mounting at the top and bringing in cool from outside the case is the way to go: "The question your probably asking is... what is the effect of using heated rad air as intake air vs setting up rad so you expel air out of it. I have tested this in past using multiple configurations and posted this on another forum. And short answer to your question, if you have ample rads to ensure decent delta ambient air to water is ~5-6C, and decent fan speed 1500rpms or more at load, then temp is going to be only ~2-3C hotter after going through rad, using accurate equipment to measure. As to effect on various computer components of rad air as intake vs expelling air out rad.... I have 280 rad in front and a 360 rad up top, both rads with push/pull fans. I used 12 calibrated dallas probes, 1 at each fan intake, and 1 in water, and 6 inside case at equidistant spread out locations, each logged per 1 second, relative accuracy is to 0.1C. I tested using 1) both rads (top and front) as intake air, (best cpu, gpu, nb, ram temps), expelled out rear GRAPHED IN BLUE below 2) both rads (top and front) exhausting air, (poor performance, not graphed) 3) front rad as intake and top as exhaust. (best mobo, hard drive temps by 1C) GRAPHED IN RED below The one that gave the best cpu, gpu, NB, RAM temps but ~1C worse mobo, hard drive and inside case temps was using both rads as intake and expelling air out back, and that is what I went with. The next best was using front rad intake, top exhaust which gives slightly better 1C or so mobo, hard drive and inside case temps, but worse cpu, gpu, nb, ram temps. The three graphs all show front rad + top rad as both intake in BLUE (air exhausted into case), vs front rad intake but top rad exhaust in red: graph 1 is prime loaded max fan speed, graph 2 is prime loaded quiet fan speed, graph 3 is prime + furmark loaded max fan speed. Gaming was too variable to test well, but average inside case temps were nearly same with either config, so again, cpu/gpu etc would be cooler just from lower ambients. The reason cpu, gpu, temps are better when pulling cooler outside air through rad is self evident... air outside case is always 2-3C cooler than inside case regardless of configuration, so 2-3C cooler "ambient" intake = 2-3C cooler cpu, gpu temps. The NB/ram temps may seem paradoxically cooler by expelling rad into the case, but it is only cooler if the top rad has pull fans inside the case, as this fan air hits the NB/ram heatsinks, and pulling air above the heatsinks seems not to affect temps much, pushing air over them makes a big difference. (MOBO and HD were either same, slightly cooler or hotter, if fan speed maxed/not and depending on location of HD relative to closest fan). The temp difference inside the case of all 6 probes comparing exhausting rad air out of case vs into the case was never more than 1-1.5C. And average between all 6 probes was typically 0.3 to 0.5C difference. Reason is air going through rads is only 2-3C max hotter air than ambient. And temp inside case is always hotter than that from heating from caps, etc on mobo, gpu, nb etc heating inside of case. Bottom line you will get 1-2C better cpu/gpu temps, variable better RAM/NB temps depending on fan speed, at expense of ~1C worse mobo/HD temps by using both rads as intakes, assuming pull or push/pull on top rad. So either configuration works fine. NOTE 1) if fan speed is high enough, mobo ambient may be variable either way by 1C depending on where you measure. NOTE 2) If doing something crazy like fully loading 2gpus/1cpu at 600 rpm fan speed, your cpu, gpu temps will still be lower by 1-2C taking in cool outside air, but then you can increase all internal components by few C by exhausted rad air in case vs out of case, but not in real world use, ie gaming at 800 rpms." http://www.overclock.net/t/1302838/does-air-heat-up-significantly-after-passing-through-a-rad/20#post_18101334

Very true rage demon. The point is though there are so many variables that's impossible to know what's best. The case itself will make the biggest difference. How close to the wall/floor/headroom under desk/carpet/ambient temperature/direct sunlight/close to the AC,How much coolant there is in the loop, fan speed profiles, gauge of tubing how many hard drives in the machine..... it's never ending. The article shows push pull is best but at the end of the day it's going to make fuck all difference in the grand scheme of things. You can't even fit a push/pull config in a lot of cases anyway! :D Nothing wrong with doing it but try to be realistic! 1-3C is not going to get you a better overclock or quieter fans. Love the maths though! :P

If you have no interest in learning how it works, that's OK, but it does a disservice to describe it as not having any value or importance. If you aren't OC, then yeah, none of this matters, including running with AIO water coolers, or any other jazz, because the chips are specced to run with air cooling. If you are OverClocking, 2 degrees C can easily make the difference between success or failure. The entire point of this exercise is how to improve the OC.

None of us have ever said it makes a difference in all scenarios, but for specific pain spots, it especially matters for 3D Vision. It's not impossible to know what is best, that's why experiments are worth doing. That's why we have science. It's not random. It may be too much of a pain in the ass, but there are things that make a difference, and things that don't. Mostly on the internet, they do poor experiments because they don't think scientifically about things. And are just looking for clicks. AnandTech used to be the go to spot for this type of hard data, but they lost their mojo. It was an interesting question that I hadn't seen an answer for- whether convection matters in a case. I've only seen people using the idea that heat rises, but never seen any actual experiments. Calculating a rough expected impact is the next best thing. It has a much bigger value than I'd expect, which was interesting. It also still has no impact once you add three or four fans.

Also GibsonRed, the higher the temperature, the more unstable the overclock as the more resistance the current has to overcome to make things work (hence the need for higher voltage requirements). This is best shown long term with prime 95 etc tests when you test to see how stable the CPU is over say 24 hours on maximum load. This isn't a spike issue, but a sustained temperature issue - here, the higher you can up the voltage, the longer it will stay stable but the more heat it will produce (again requiring more power to remain stable). A 3 degree difference can be 0.05v which is the difference between 1.45v and 1.50v, which makes a tremendous difference in long term and sustained stability when overclocking :)

The point of diminishing returns was hit way before a 0.05v CPU core voltage reduction. Sorry for playing devils advocate but de-lidding or a slight increase in pump or fan speeds will give you far greater returns than turning your fans round or moving a radiators position in the case. Water cooling over aircooling is hardly worth it from a performance point of view anyway. Noise maybe (that's the reason I do it) but it's a lot of effort expense, work and maintenance that doesn't really justify the end result IMO My next case is going to be this beast. No water and no fans with high performing components....... http://www.kitguru.net/components/cooling/dominic-moass/kitguru-looks-at-the-calyos-nsg-s0-fanless-chassis/

Cool case by the way.

@GibsonRed: You are a strange man GibsonRed. You drop in a completely unrelated topic, then tell us we are all doing it wrong, and only you know the true answer. However, this is your MO. There isn't one of us, not one, that said word one about push versus pull. You pulled that out of your hat, and derailed the conversation. I suspect the real problem is that you simply don't read what we write. Fair enough. I'm done responding here. @tygeezy: That 10 degree difference is real, and will in fact make a gigantic difference for an overclock. The key point though is that it's cold air versus warm air, not the actual location of the radiator. That was my beef with the video you posted- it would have been even more interesting if he'd flipped the radiator on top to pull in cool air. That's why I mean by being scientific. He tried the two most common layouts, but didn't go past that. It's hard to learn new tricks when he doesn't finish the test.
