I use a AC fan pointed into the case on high when I run prime95 because like I said very little loads it that much and that long. So unless your folding or doing huge video editing/encoding you won't be loading your cpu that hard that long.
What is your primary use of the computer and do you plan on OCing further? For many people there is little to be gained above 4.5GHz without paying for it with heat but if you are only gaming you could shut down hyper-threading and save 5-10c in some cases.
I think you are sitting pretty though as long as you plan on leaving it at 4.5GHz because as the person above mentioned that proc can go much higher without major issues.
I game and render. Well if you say I can go higher I mean why not? How high do you think I can get my processor?
For most people it starts to get very costly in the vcore department very quickly. IMHO it isn't worth a 10% gain in performance at the cost of a ton of vcore. You may be lucky to find out you can OC fairly high without to much vcore or you could be the type to throw caution to the wind. Or you may be in a position where you can afford the best of the best of the best and that means a mandatory OC and even if you break something it was worth getting the best of the best. Whatever the case those are all ok to be I used to be a throw caution to the wind guy now I am a stop where the vcore starts increasing exponentially kinda guy. In other words I have hit speeds higher than 4.5GHz on my 2500k at vcore that people claim are safe but I choose to back down to 4.4GHz because just the diff between 4.4 and 4.5 was several steps up. At 4.4GHz I am running using negative vcore in the asus motherboard settings. Now it isn't truly below stock vcore because I enable LLC but you get the idea. Just to go to 4.5GHz I have to go 4-5 clicks up, that is a very safe voltage but... I don't see 2-3% gain in performance worth a much larger increase in vcore. The same can be said for my i7 920 I run it at 3.8GHz liquid cooled with a full board block and I have gotten it stable to 4.2GHz with lots of head room.
If you find yourself the type to say 5-10% is worth the risk then do it. Also there is a huge difference between people who find the highest stable OC say for example 5GHz or whatever and then back way down and the people who find that highest stable clock and run it 24/7.
When you ask how high do you think I can get my processor it is this question that nobody ever really wants to answer. It is almost like tabo for some one to answer that question. When I first came onto this forum and over clockers. My first questions was hey tell me some magic questions to throw into my Phenom x4 2.2GHz proc. Now I realize it just isn't the case. I can say that most 2ng gen i5s and i7s will hit 4.4-4.5 with very little to no vcore increase. I don't know if that hold true for your chipset. What I do know holds true with all chips is you hit a brick wall made out of vcore at some point and at some point you find you are adding many more steps of vcore than you had with the previous multiplier.
So are you happy with the 4.5GHz? Would 4.8GHz really be a big deal for you? If the answer is NO and YES then carefully start looking for that higher clock. I know when you are reaching the end many little adjustments may come into play I really learn't that OCing the 1st gen i7 and it held true for the higher clocks on my 2500k.
So sorry for such a round about answer but like I said not many people are going to come right out and say this is what you should get on the cpu. Because all the CPUs are different and it is like playing CPU lottery. IMHO you won the CPU lottery as far as heat is concerned. A lot of people found the 2nd gens more favorable for OCing because of heat issues on the 3rd gen. You are obviously not having this issue. Now I doubt that just because you got the magic lucky chip as far as heat is concerned that the same will be true about the max OC because I think the heat issue has more to do with the IHS than anything else.
I hope that helps maybe it doesn't maybe it does.
OH bye the way I just noticed something I said previously may be misleading. I said "as the person above mentioned that proc can go much higher without major issues" I was talking about HEAT not the max cpu speed. It doesn't go too much higher then that I mean 5GHz is rough for a lot of people and that is just a lil more than a 10% increase in speed. But if you want to at least see if you can hit 4.6, 4.7 4.8 with very little vcore then go for it. Who knows you may just get lucky enough to find your way to 5GHz. Also on the 1st gen turning off hyper threading not only decreased the temp it increased how far you could OC it for some people. This may hold true for you or it may not. Hyper threading doesn't help in games but it does in some other places.
How long does a "render" take. Are we talking seconds, minutes, or hours or even days? I know that 10-15YRs ago whenever pentiums where on a card socket and not a socket socket final renders took days! I don't do that stuff anymore so I have no idea what you are rendering and the time it takes. If you are rendering something that takes HRs then what the guy mentioned about your heat in prime95 needed more than a few minutes is very valid. This is of course only if your application is capable of hitting 100% CPU utilization. If it is not then the heat on prime doesn't really matter and I would use a fan to keep it fair and cool.
There is no task that I do that has me going 100% for more than 15-45min
Don't know if that is the same for you.Edited by givmedew - 11/6/12 at 3:54am
