I see alot of threads here with comprehensive information regarding different boards, different clocks, and how they were obtained, but one thing I struggle to find is air cooled i7 temperaures, what they were achieved with, and what the temperatures are like in real world applications.
Perhaps we could start some form of table / system to keep a log of this?
I know it would be a great help to people like myself, who are tossing up air and water cooling, and would love to see other users results.
So if people start posting their clocks, idle temps, load temps, real world usage temps, and what air cooler configuration it was done on, I will start a database here!
P.S Am I realistic in hoping to get 4Ghz stable air clock at reasonable temperatures?
Cheers XS!

You are able to get 4Ghz 24/7 with good air cooling, a TRUE120 with good fan/s is the best.
Right now im still testing my i7 920, P6T Deluxe and 3x2Gb G.Skill 1600Mhz CL9. I was only able to get 3.9Ghz Stable for now, im pretty sure im being limited by the 920 itself. Right now im trying with even more voltage, 190x21 = 4Ghz. Ill post later if i get good news.
Still, im pretty sure, with a good Batch you can get 4Ghz easy, even more, i saw some 4.2Ghz on air around here.

i7 920 @ 4.0 / 20*200 / HT ON /Speed-Step OFF / 1.375 Bios / Gigabyte UD-5.
Batch#: 3837A768
Cooler: Akasa AK-967 with push/pull layout 2*1600rpm 56CFM fans.
Idle: 33/33/34/35
Load: 71/71/72/75
Gaming: Around 56 max, nothing uses the CPU.
Configuration: Modified case, 5x80mm exit fans, 3x120mm side fans. 2x120mm front fans. All under 70CFM and 30dB.
Heatsink cost £28 and the fans where all under a £5 from PCWorld UK/or the ones i've got free with a heatsink...

I reach 3.8~3.9GHz very easily, but 4GHz is very hard. I don't know if I'm limited by my board (5 phases PWM), the temps (not the processor itself but other board temp) - it's summer here in Brazil now - or the processor itself.

batch 3836A977
Being on air, with HT on the heat quickly overwhelms the chip. Since Intel no longer makes i7 920 with AC characteristics like this one, this chip is literally irreplaceable so I won't take a chance on damaging it with 95+ C temps. The justification for leaving HT disabled is that HT does not increase performance, but the extra clock speed I get from leaving HT off does. This translates into a very tangible real world benefit...I can and do run 4011Mhz at only 1.184 Vcore 24/7, and my CPU generates so little heat that I can crank my CPU fan down to inaudible levels so while doing anything on desktop, I can barely hear my computer, like "is this thing running"?
If I can prime at 4011Mhz @ 1.184 volts, what can I do at 1.344 volts? This validation run heated up my cores to around 88C

Roller,
Your problem is the Tuniq.
That heatsink can't handle a quad core. The heatpipes vaporize and get so hot they can't condense again properly, so temps skyrocket.
If you switched that Tuniq with a well mounted/secured TRUE 120, you will see a 10-15C temp drop.
I got a 10C reduction in Prime95 just by switching from Tuniq to True 120, and over 15C temp drop in Intel burn test, and this was on QX9650 @ 1.3825v, 4 ghz. It actually peaked at 92C in IBT, before I guess #Thermtrip kicked in and caused a lockup with a horribly screeching so bad, it would wake the dead (as well as anyone in an adjacent apartment!).
With a TRUE 120 at that same voltage, peaked at 69-70C :)

Running your QPI Link speeds @ 2400 wouldn't hurt the overall overclockability of the chip either.
If it can't do 4.2+ghz with HT on it's not worth a piss unless it's used for pi runs exclusively.

Out of curiosity's sake....
Has anyone tried a core i7 on a ZALMAN CNPS8700? I ask b/c many people might wanna run a mATX mobo and in cases like a sugo sg02 for example, there's only 78mm of room. This is supposed to be the best cpu for that kind of space.
Anyone wants to see what it can do cooling wise?

system in sig....tried the Cooler Master V8...it does well for gaming, but running prime or anything that brings up some serious heating, and it can handle it goes to the hi 80s.
4.011 no HT....1.4375...idles all cores in the 40 to 43 range, with occasional drops into the high 30s when ambient drops ( winter heating here right now so depeneds how much the heater is running etc)...and loads gaming the highest ive seen of 49-54 across the cores.

It depends on the individual processor more than anything really. If you get lucky and get a good one that doesn't need much voltage then 4Ghz is easily achievable on air with a good cooler.
Batch No.# :3839A611
Idle Temps (Per Core) : 36/36/35/35
Load Temps (Per Core) : 64/64/62/62
Gaming / Real World Temps (Per Core) : depends on the game, typically one core is around 50-55 and the others are around 40
Air Cooling Configuration : Noctua NH-U12P SE1366 with 1 fan attached
I should also state that my ambient temps are 17-18C for anything thinking my temps look super low. I like my room to be an icebox, what can I say? :D

WOW! Ya know, I was thinkin' that cause I couldn't understand why I do so well with HT disabled, and temps overwhelm with HT enabled. If I go to a new cooler, it won't be the True, it will be the ifx-14 by Thermalright. reviews I've read show it to beat every other air cooler by a wide margin.
Anyhow, thanks for the excellent response.

I can also vouch for the mugen2 I installed it on my i7 920 @ 3.84ghz 1.232vcore LOAD and the thing cools amazing! It keeps it under 70C!!! all 4 cores under 70C when running WCG crunching... HT ON!
As far as mounting it...it was a pain, but it sure was fun! lol...interesting mount design, if you swap processors often I would recommend against it unless you are ok with taking your motherboard completely out and turning it upside down to dismantle heatsink every cpu swap =)

From what I've read, the IFX is only better than the True with low speed fans.
Otherwise they are a bit equal. I'm not sure if the mounting system is more secure than the regular TRUE (to stop it from swiveling when pressure is applied), but there are several good alternatives out. Why not give Thor's Hammer a try? IMHO, the IFX-14 is overrated. But perhaps you can ask Vapor about that....

Man, I'm seriously looking forward to getting my system up and running. Right now it's sitting on the kitchen table waiting for some cables and a replacement fan. I'm hoping to hit 4Ghz, I'd like to hit 4Ghz on the 920 in a 24/7 capable config. We'll see! 3.8Ghz should be easy.

IIRC, I ended up finding something about as high as the heatsink, I think I used the heatsink box and basically I put the heatsink next to it, upside down. I then flipped my board upside down and rested it on the box and heatsink (heatsink in right position) and then I lined up the holes with the new mounting bracket on back and then put in screws and tightened them down...it went pretty well =)
That was the easiest way for me...that way I did not have to try to hold things in place on both sides of the board at the same time lol!

oh and your processor with its thermal grease will already be in socket and applied =) when you put motherboard upside down on the heatsink
I was actually a noob, and first time I screwed down the heatsink I totally forgot to take the protective plastic thing off the base of heatsink ( I left it on there as long as possible while heatsink was upside down because didnt want dust and stuff on it) but right before flipping mothreboard upside down on it, I forgot to take it off ROFL!!! then I flipped it rightside up and noticed the plastic was still on base and was like OH SNAP! hahahaha...
had to disassemble and reassemble...this whole thing made me laugh and made it fun hehe!
Luckily I had enough arctic ceramique left to apply 2x =)

I dont know, I have always liked it better and I have read it can cool better than AS5 does.
Its not as thick as AS5 and has an easier time spreading evenly also.

Yeah I think ceramique does as good or slightly better than AS5 on rough or uneven (convex/unlapped HS or IHS?) surfaces, while AS5 does better than ceramique on lapped surfaces. HDT coolers I think need AS5 or that IC7 diamond stuff as white paste (including ceramique I think?) can oxidize copper?

Still very happy I am at 20x195 3.9GHz running LinX for 30 mins so far temps 55-55-54-52 (case covers on) room temp guessing around 20c.
