case scenario, you run an absolutely insane overclock for a year and then you have to drop it 100mhz due to degradation, and that's max voltage, max temps, running at that at 24/7 (ie like running prime95 24/7). So like a 4770k at 1.5v at 90C for 24/7 for about a year straight. Of course haswell hasn't been out that long, who knows, but based on previous sandy bridge iterations and all indications of haswell.
I mean it's pretty straightforward with these sandy bridge-based cpus, you dont really get any death or degradation until you approach ~1.45v+ with 85C+ temps, it's just unheard of on anything much less than that.
So. Worst case scenario, 6 months later, 100mhz lost. 100mhz that you wouldn't have ever gained anyways by playing conservative, and an extra 100mhz enjoyed for a year, a value itself. It's still a perfectly capable chip, and you could still sell it for it's full value on ebay, market, cl, etc just fine. CPUs tend to sell for near-identical price to new price at a retailer, often times even more than, due to the extremely high level of support companies like Intel give (they honor RMAs and warranties no questions asked, no receipt necessary, in practice - you could literally RMA your chip if it degraded, though it would be plausible they'd deny a claim of "it used to oc to 4.9 and now only does 4.8', intel being intel, they'd probably still take it, though obviously that's not not kosher).
As long as the chip is capable of hitting it's rated stock frequency, you can sell it for it's full market value on ebay easily (10% paypal/ebay fees and ~$2-3 shipping domestic), it doesn't really matter if the chip is now doing 4.7 instead of 4.8 like it used to - of course, an honest seller would mention that the chip is used, but as long as you do that, it's fine, and you can get $400 for your i7-4770k. Assuming a degradation of 100mhz is just so terrible.
I'm not saying burn your chip but... if you have a water cooling loop, burn your chip. It's like buying a lambo just to get the groceries. What you should really do, is sell your custom loop off, buy yourself a still-decent heatsink like a LQ-320 or Logisys Assassin, and then give your retirement wiggle room (if it's really so tight that a cpu would ruin you).
I mean remember, there is a HUGE market for 'broken/for repair' components. Even if you took a hammer to your CPU, you'd still get around $100+ for an i7-4770K. I know I've spent plenty of money on clearly broken components and fixed them myself and saved myself a lot of money in the end - things that had blown capacitors and I simply soldered them back on, blown voltage regulators that I replaced on the board, broken pins on AMD CPU that I replaced with ethernet wire stuck into the motherboard pins. So if you literally 'break' your CPU, you aren't out that full $400 or whatever it cost you, you are more like out $100, if that.
Degradation and death comes from temps and voltage, you get that at stock just as you get it at overclock. The stock setting is literally just an overclock the manufacturer decided to sell the chip played against the increased/decreased price of a higher/lower cpu speed sold vs returns of faulty chips that are unstable at that 'overclock' (or clock really, but just to illustrate a point). If you are running a custom water loop, you have your chip so cool that you can basically do any voltage below ~1.45v as long as you stay below 80C and be perfectly practically safe (and I'd say sub-1.45v and below 85C for 'normal, non-super conservative people).
I'm not saying run bleeding edge and push everything to the limit, but why buy an i7-4770k if you aren't going to really overclock it? Why not just get an i7-2700k/3770k or i5? Why did you buy a custom loop? You literally bought lamborghinis, but then aren't driving them past 60mph. I could understand if you had an i5 or sandy/ivy maybe, and a standard air/clc heatsink, but I don't get why you'd buy top of the line stuff and not utilize it.
Like literally, my i7-4770K + H110 for half the cost of your system, performs better than yours. I just don't see the return there. For less performance, spend less. I wouldn't spend more if it didn't give increased performance, or if I didn't plan to utilize that performance (and if you say '100mhz means nothing', why did you buy an i7-4770k instead of an i7-3770k or even 2700k, why are you using an i7 at all if you aren't doing cpu heavy stuff?).
I hope the best for you, I don't mean to go on this tirade against you, I just see this 'mentality' a lot and this is my reaction to it. I wouldn't say all of this if you were just an i5 + hyper 212 user. Literally, a high overclocked i5 + lq-320 will outperform your i7 + custom loop system in most tasks.
