Worried about i7 heat.

[michael19]

I'm looking to buy a new setup right now and i'm looking at the i7, i know it's been discontinued but i'm not someone who is worried about upgrading every 6 months (or even every year) so a discontinued processor is fine with me as long as it's a good performer.

The thing i'm worried about is I don't want a mini heater in my room. I will be getting a lapped TRUE Black 120 with a nice fan and some mx-2. But i've seen that 35-45c is a normal idle temp for the i7.

I'm wondering what other people i7 temps are, and do they produce a lot of heat in the room? I'm thinking of just waiting for the i5 for the less wattage draw and hopefully less heat. Or if i'm not patient i'll just get a Q9550

Again, I really don't care if I get the discontinued processor because the socket will still be good and the i7 is a very goo performer. I'm just worried about the heat! So let me know how the i7 heat has been treating you.

Wrong.

The product line may be reduced to the Extreme processor(s) only (will more be released - who knows??) later this year, but the I7 is not being discontinued.

You will probably find that if you go for a high end GPU, it kicks out the same, if not more heat than the CPU does (both at stock). All I need to do is place my hand on the exhaust of my HD4870 X2 with the fan at 100% and it warms my hand quite nicely.

It also depends on whether or not you are wanting to overclock whatever CPU you buy. The higher the over-clock; the more heat generated. If you are running it at stock (or nearly stock), then I wouldn't worry too much about heat.

Edited to clarify what I was saying.

Yes they create a lot of heat, but the architecture is not inefficient (unlike the p4, which just created a lot of heat). At idle usage (99% of the time) the heat won't be a problem.

Ah yes you're right. I meant to say the i7 920, not the whole i7 line. And i'll be running it at stock, and if not then just bumping it up a little with no voltage increase.

Thanks for the input guys. Anyone else?

 

[taltamir]

i7 is way lower temps than anything AMD makes... and for that matter its thermals should beat the C2Q as well.
i3 and i5 will not have better thermals than i7. (actually their differences are negligible)

I would recommend a P55 based board with an i7 (or lower depending on final pricing) since that should improve thermals by integrating the remaining portions of the northbridge from X58 into the CPU.

Heat shouldn't be a issue with a true 120 though. And if heat still is a issue for you then disable HT and heat will go down a pretty good bit.

I been using a Zalman 9500 AM2 heatsink with the 1366 bolt on and on normal clocks{stock} it cools okay but around 4.0 ghrz it get hot. If i remove HT it drops it by 20° easy at 4.0ghrz. But i just picked up a "Prolimatech Megahalems CPU Cooler" so now i should be in the nice and cool world.

 

[taltamir]

20 degrees drop with no HT on idle or load?

because if it is on load i am guessing it is because your CPU is just doing less and you are actually less efficient, not more.

In fact it will be more of an issue. Then he will be more efficiently heating his room.
Personlly I'd go for a Q9550.

okey what the hell did u do to get a 20C increase from HT on to HT off.

reread what he wrote... 20 decrease when he turned off HT-- this has to be during load.

Okay, I've seen you go around spout this too many times. Your understanding of the i7 is incorrect whereas the "new i7" is not the i5 or i3.

The Core i7 is NOT compatible with P55 chipsets and motherboards, the Core i7 is a Socket 1366 processor and will always be one, while the i5 (and i3 I believe) are 1156 Socket processors.

You're only confusing people who don't know what you mean when YOU talk about the i7, because you mean the i5, and it's getting ridiculous that I have to point this out to you.

On topic: I wouldn't count on i5 producing noticeably less heat but it's too early to tell. My i7 at currently 3.6GHZ (damn summer) runs idle at 36 to 41 degrees and under full load up to 62C.

 

[taltamir]

I don't mean the i5, there is a clear difference which I explained in detail.
INTEL has decided to call multiple chips the i7. There is the s1366. the s1156 i7, and then there are the laptops versions. They all have their differences.
What YOU CHOOSE TO BELIEVE is IRRELEVANT! Really, the world couldn't care less.

The fact of the matter is that intel is releasing an i3, i5, and i7 to the s1156

 

[jandlecack]

Direct me to that press release if you would.

What you speak about is a rumor at best. The latest word was:

"Currently, Core i7 processors use the new socket 1366, while in the third quarter of 2009, Intel will launch Nehalem-based mainstream desktop PC processors based on socket 1156."

Newsflash: Mainstream Nehalem is Core i5 - a chip without QPI and instead IGP. There is no Core i7 chip for 1156 sockets and there has not been an announcement of that sort.

Also, post glitch.

 

[taltamir]

lemme copy paste, AGAIN the exact detailing of a mere tiny PORTION of intel's new naming, and analysis.

an i7 for a desktop is defined as a quad core with hyperthreading (8 threads).
an i5 is either a quad core with no HT (4 threads) or a dual core with HT (4 threads)
an i3 is like an i5, only with turbo mode disabled.
Laptop definitions are different than desktop definitions.

The P55 will have an i7, which actually has some advantages (along with some disadvantages) over the X58 i7. it is a slightly different design but it should compete well. and be less expensive.

the differences between P55 i7 and X58 i7:
1. memory channel: X58 is triple channel DDR3. P55 is dual. (this actually an arbitrary choice when designing the socket, and has nothing to do with the actual physical chips titled P55, X58, or ICH10; ICH10 works along with the X58 chip, the P55 is a single chip solution)
2. P55 will have a single full speed video card connection, or two half speed connections. X58 has two full speed connections. So if you run SLI/xfire X58 is better
3. P55 has the pciE video connection integrated into the CPU, improving latency. As long as you only use one slot (so you get full speed connection) than the P55 will actually be FASTER than the X58.
4. turbo mode: there are unconfirmed reports of P55 having greater turbo mode boosting.

While triple memory channel is good for a high IO fileserver, it makes no difference in GAMES and regular programs.
So for a gamer: 1 makes no difference. 2&3 mean X58 is better for multiple cards, P55 is BETTER for single card. and 4, if true, means that P55 is much better for video games.

 

[jandlecack]

You're clearly a moron.

The "i7 on P55" you so happily claim exists IS THE CORE i5.

I'm sick of arguing with an idiot, please take your crap elsewhere and stop confusing newbies.

 

[taltamir]

no, the core i5 is quad core with HT disabled, or a dual core nehalem. Intel says that they can easily make one for the X58, but do not intend to at the moment.

 

[Trevelyan]

I wouldn't worry about it... the new 3rd party heatsinks are big, but they keep the cpu quiet and cool.

 

[yh125d]

Gonna bookmark this for when Intel introduces 1156 i7's

Until you point me to a press release, this is unconfirmed rumor and nonsense. Stop trying to validate your theory without proof.

Read what we are talking about.

He claims there will be a Core i7 built for P55 Socket 1156 architecture that isn't dubbed Core i5.

Did you read the links?
"For example, upcoming processors such as Lynnfield (desktop) will carry the Intel Core brand, but will be available as either Intel Core i5 or Intel Core i7 depending upon the feature set and capability. Clarksfield (mobile) will have the Intel Core i7 name."

 

[jandlecack]

That quote can be interpreted various ways, but even if they call a stripped down Bloomfield on Lynnfield basis a Core i7, there is no further mention of chipset whatsoever. There could be an X58 S1156 in the making, or there could be a Lynnfield "Core i7" for the Socket 1366.

My point is that recommending to wait for the "i7 on the P55 motherboard" is a dense and narrow minded suggestion that totally misleads people who aren't sure about chips / platforms due to the fact that nobody knows how the chips will actually be released and how they will perform.

If you want to recommend a Core i5 then recommend a Core i5, not a hypothetical Core i7 on P55 that could go either way since it's nothing more than a pimped up i5.

Lynnfield's TDP is reportedly 95W, and desktop Bloomfield's (current i7) TDP is 130W. There are trades (such as number of memory channel, on-board/on-package PCIe, QPI, etc.) but it seems reasonable to assume Lynnfield will run cooler than Bloomfield given the same performance. Plus P55 boards should be much, much cooler than X58. It's sorta similar to what Intel has been doing. e.g. 975X -> P965, X48 -> P45.

Heat and Performance/Watt are different things, despite being closely related often times. Personally I'm less sensitive to power usage than to heat/noise as long as my PSUs can handle the load. Devoted F@H folks might have different preferences..
