Do I seriously annoy you that much?
Yes, and then some. If you are going to post on a Forum that is populated by people that, in the main, post informative or well reasoned information, then try to do so. So far, you have abjectly failed to do this.
Overclocking a device is not guaranteed to decrease the lifespan unless thermal control fails to be improved in tandem.
When I worked for NVIDIA, our testers said an increase of 10°C in continuous operating temperature would halve the remaining lifespan of a device. An increase of 20°C in continuous operating temperature would make the lifespan a quarter of the 'normal' lifespan, etc. Since most Intel CPUs have an operating range of 30-70 or even 30-90°C, you can see what difficulty you'd have in determining "normal" life span of a device.
Granting of warranty returns, at least at retail level, are not really affected by the competent overclocker. It's very hard to detect damage from overclocking (thermal failure) instead of other kinds of gate failure or buffer failure--well, that is unless you're dumb enough to leave the chip pads modded or scorched when you return it. One pretty much has to cap the chip and look inside to determine the cause of failure (which no retailer is able to do).
I'm quoting the whole block,
because it is perfectly correct. Read this, try to understand it, and you may see why I take such objection to your ill-informed posts.
Overclockers with even a single braincell will have cooling that will blow your mind (and the rest of the kit will make your wallet cry for mummy). Anything from Air cooling with insane CFM (My preferred route) to Phasechange cooling at well under -100c. We
know heat kills chips, and trust me, we go to great lengths to avoid it.
After a buying spree to find a great cooler for that aforementioned XP1700, I gave away nearly 20 top-end air coolers, having bought and tested in many configurations every single one of them. The difference from worst to best purchase was in the order of 10c under a very very heavy load. only the best will do when you are going for record. Kind of like the inhabitents of this forum, and our tastes in keyboards.
Neither have I. But I have never overclocked a microprocessor either.
Try it. With your kit, it'll either make a huge difference, or I'll see the fireball from here in the UK. Personally, I think that watching the latter would be more fun.
@Ricercar
I'll agree with your sentiments on KVM's. One Keyboard and Rodent per box. I actually tried giving away a fully functioning USB KVM here, but it seems most share your feelings as well.
