If you can pass this it's stable, but then again even the most stable OC can have issues when folding (if you decide to do that). Games don't really stress a CPU much, they're heavy on the GPU.
Just a note. Many games do work out a CPU quite well. Battlefield 3 is a good example. It would make my Core 2 Quad max out (even with 2 x HD6970 in cfx), which is why I bought an i5.
Although this guide is from OCN, I don't feel like looking for it so I will link to it on Tom's Hardware:
He says lower in the article that
"TJ Max for Ivy Bridge is 105C, however you shouldn’t go above 85-90C load when overclocking."
Which seems pretty reasonable.

Set the stress level according to how much memory you have. This will further increase your load temp so keep an eye on it. My system temps are based on the highest setting (70c at 4.5GHz on an i5 2500k). I set myself a 73c limit for my cpu for maximum sustained temperature, and then set the clock to achieve that using my H100 cooler.

There are so many decent fan controllers that it's hard to just recommend one. Your best bet is to check out a few websites like Tiger and Egg, select a few you like, and then ask opinions.
In general though, you should look for a controller that has decent wattage per channel (this will allow you to connect more than one fan per channel if you desire, or connect high wattage fans).
Also, there are a few control options. Some controllers use buttons, some use knobs, some use sliders, some use touch screens. Some come with temperature sensors, some will control 4-pin PWM fans and some only 3-pin fans, and some will control both. Some controllers have displays to show RPM and /or temperatures. Some take two drive bays, some take one, and some are internal.
How many fans do you need to control? What type of fans are they? Do you want a minimal design or something a little more showy?
I've personally gone through about six fan controllers over the last two years, from different companies. All had their good points, and all were pretty different from each other. Right now I'm using this:
If I could have found it, I think I would have bought this one:
Note that neither of those are high wattage per channel controllers.

One direction will be intake and one will be exhaust. If you want positive pressure than make them intake, just be aware of dust issues (I recommend a dust filter on each intake fan). Intake should be fine in most instances for fans in that position.

I'd like to see your vcore at high 1.2**v or low 1.3**v for a 24/7 OC w/Ivy, just my opinion though
Also consider the "long term" stress on your motherboard at those voltages/temps.
Warning: Spoiler! (Click to show)
And if you run IBT at this voltage your temps could go well above 100c. IBT typically will raise temps 5c-10c+ higher than P95. Even if your main purpose is only gaming (max load 70c) I wouldn't want my P95 load temps higher than 80c-85c max for overall stability even with your somewhat high ambients (27c-30c) ... And for many of us w/more typical 22c ambients we usually strive for no more than 75c load temps for overall 24/7 stability. So I'd lower my vCore/OC until I achieved that threshold. I could go on and on but I recommend you read up by searching this thread with "IBT" like HERE HERE
Or you could reconsider D-liding your IB processor, some results are nothing short of amazing ... same goes for Haswell for all those that are debating an upgrade from Sandy ... SEE HERE

You may find THIS LINK
pretty helpful as well. It deals directly with a 3570K and how to become truly gaming stable with P95/IBT/Furmark etc. Very informative blog and he echoes a lot of what I've experienced building mid-high end rigs. To say that gaming doesn't stress the CPU much these days is a misnomer ... BF3 64multiplayer or even Serious Sam 3 anyone?
Doing this could push his temps well over 100c for "extended" periods of time ... not recommended.
I think what you meant to say here is "something with cooler CPU load temps for 24/7 use"
because you can be stable at very high vCore but do you really want 95c+ temps 24/7?
EDIT(s): My apologies for not making my points "clear" (er) without writing pages of info ...
Hope you get the idea and you find this somewhat helpful

Asaka has always been an ok brand for fans. Have you considered just using a PWM splitter with PWM fans? That would keep costs down by not requiring a fan controller, and automatically control the fan RPMs.

Are both fans 4-pin?
By "the same result", do you mean the same fan was acting up or the same port was acting up?Edited by Mergatroid - 7/3/13 at 7:16pm
