Does a 'Push-Pull' Setup Decrease CPU Temps?

Slightly, as in only a few degrees (1-5C), at most, and only under load.

So your saying that an extra fan wont do much good?

Im planning to OC 3770k to 4.5ghz... can the tpc 812 with single fan take care of the temps?

Not necessarily saying it won't help (I use push/pull on my 212 Evo, and it's around 4-5C cooler than the single fan), but the TPC 812 should be fine with the single fan. Adding the extra fan won't make or break the OC, just help it run slightly cooler.

What If i add 2 cooler master sikleflow's to the tpc 812, will the better fans help in reducing temps?

They're good fans, for sure, so they'll help a little more than the stock-type fans for the TPC 812 will, but you'll never get anywhere close to a 10-15C difference or anything. Push/pull helps, but it's not a miracle worker.

depends on your fans. the better they are the more effective they will be. dont bother with any fan that gives less than 75 cfm... its also more effective if the second fan has a slightly higher cfm to compensate for the pressure drop from the air flowing over the fins. its not essential but will increase efficiency a little (1'c).

Is it Possible to OC 3770k to 4.5ghz with the tpc 812 and 2 sikleflow's or can i only OC to 4 or 4.2ghz?

People say 4.5ghz on air causes thermal throttling for the 3770k.

Possibly to 4.5. And with lesser HSF's, it does throttle at 4.5 http://www.tomshardware.com/reviews/ivy-bridge-overcloc...

I would get Kuhler 620 instead or the H60. 620 is better. Also, the TPC isn't actually that good if you were hoping for something really high end.

Disagree with closed loop water (just pointless, IMO), but definitely agreed on high end air like a Thermalright Silver Arrow or Noctua NH-D14. Otherwise, custom water is the best way to go.

That, and they don't perform any better than a medium priced air cooler, usually. The H60 is just on par with a 212+/Evo, even.

For my money, I'm just saying I would never waste my money on closed loop water. High end air or custom water are the two best options. The only real reason to go with closed loop water is space constraints (and with a larger Rad, even that is questionable).

The nh-d14 is out of my price range :( 

can i OC 3770k to 4.3ghz with push pull using sikleflows's? maybe even 4.5ghz... on tpc 812

Yeah, 4.3 should be fine, and you MIGHT be able to do 4.5, but you'll just have to try it and see.

If i buy noctua nh-d14, will i get better temps? or will the tpc 812 be enough

Yes, definitely. 4.5 might still be pushing it a little, I believe, but the NH-D14 would have a MUCH better chance of doing it at semi-normal temps than a TPC 812 (push/pull, or not).

My Cousin has a 3rd fan attached to the d14!

How is this possible? will that 3rd fan decrease temps?

Yeah, you can add a third fan because one of the two it comes with is sandwiched between the two radiators. And yes, it should help lower temp some (but again, it won't be anything close to a miracle, just a few degrees, at most).

In that test yes, but the 212 Evo is less than a degree warmer in the first one you linked and only 2 degrees warmer in the second, and we all know that's not true in the real world. They're not doing real world tests there, just a hot plate type test.

I think it is personally, but I think you'll be ok with the TPC 812, just on the edge, with possibly uncomfortably warm temps at 4.5.

Temps aren't really going to matter as much as the physcial CPU itself when it comes to reaching limits. CPUs don't throttle until 90C+, and you have to be pushing a lot of voltage to do that. High temps can cause some instability, but often you'll hit the wall before temps are an issue, if you're using a decent cooler. Sure you might get a couple degrees cooler using more fans/faster fans/bigger coolers, but it's still luck of the draw with the CPU - and motherboard, for that matter. Needs to have good VRMs/power phases.

If it was me, and the case could fit it, I'd get an Archon.

The TPC 812 would be right about the same as the NH-U12p and slightly better than than V6 GT.

Keeping the temps lower in the case will likely do more for cpu temps than an extra fan on the cooler.Thermal flow is far more dependent on temp differential. If you have a gpu warming up your case, you will have to address that issue.
