My temps seem high to you?

[Rakewell]

Greetings all,

Just built a new system with the following specs:

EVGA 680i
Intel C2D 6700 OC @ 3.5 Ghz
OCZ Platinum Revision 2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800
(4-4-4-15)
BFG 8800 GTX
Zalman 9700 cooler
yadda yadda...

Idle temps: 38-39 c
Full load temps: 61-62 c

Here are my voltage settings:
CPU Core - 1.4
CPU FSB - 1.3
nForce SPP - 1.4

I don't have AC in my apartment, and it is a bit warm in here (78F)... Should I be concerned, or are these acceptable temps?

Also, I was going to OC my memory (for whatever reason, my MOBO lists the RAS to CAS as 5-5-5-15). As a bit of a 'noob', what is the benefit to lower RAS-CAS settings?

Cheers,

Rakewell

More memory bandwith, I think ... In general it should make things faster. About your temps, hmz, they are acceptable, but a bit to high to be comfortable. You really don't want your cpu to go above 65, so if the ambient temp goes up you'll hit 65c quite fast. How many casefans do you have ? And did you use orthos or tat ? I also hope you disabled stuff like cool & quiet, just keep that zalman runnig at 2800rpm.

Oh, and in my opinion, if you used TAT, most things you do won't get your cpu running as hot as it will when you use TAT. Best bet would be to play whatever game, or run whatever application you have is the heavyest, log temps, and see what happens.

 

[Rakewell]

Thanks for the reply~

I use Orthos for stress test... since I wrote that first post, however, I had to up the CPU Core to my last setting (1.4375) as the system rebooted during an Orthos Test. My updated temps are 40c Idle, 63c full load...

Maybe too high, huh?

 

[MarcVenice]

It's definately pushing it. Although I myself can't get my cpu temps up to what orthos get's it too, and I bet many others can't either. Unless you multitask a lot, with photoshop, video-editing and matlab and all that kind of stuff, then I can imagine your cpu running as hot as it does with orthos. So it's up to you. And err, how many casefans you got ? The zalman seems to be a good cooler, but there are better ones.

 

[Rakewell]

6 case fans, 1 Zalman CPU Fan, and the PSU... Seems like a lot (of course, it is pretty warm in my room as it is [26c!!!])

 

[MarcVenice]

So you've got the cooling worked out

I don't know what you are aiming for, but I guess you will have to be content with 3.4-3.5ghz. Maybe its better to run at 3.3-3.4 if it means you can lower the vcore as well and have load temps at or below 60celsius.

 

[Rakewell]

Do you think there will be much of a performance hit, going from 3.5 to, say, 3.3?

 

[BonzaiDuck]

I'm running an E6600 OC'd to 135%, or 3.24 Ghz. My top-end temp under Orthos -- using an open test-chassis and therefore not MY optimal cooling environment -- is around 43C with room-ambient at 70F and no higher than 47C with room-ambient at 75+F. It won't go beyond 50C even if room ambient goes to 80F. (and if I have to live somewhere such that even AC doesn't keep temps below that -- I'm freakin' moving to Alaska to wait out the great global warming catastrophe.) I"m expecting a load temperature below 45C at 75F ambient when my case-mod project is completed.

[I'm in So-Cal, and I pray to all the forces of the universe for 20-foot snow-drifts in July -- to encourage all the sun-worshipping spend-thrifts to sell off their real-estate at reasonable prices and move to Cabo. I HATE the summers here!! ***** all that **** about "Sunny California."]

I'd like to say that you might have been better off getting a ThermalRight Ultra120 (or better, the U___-120 Extreme). Those coolers blow away the Zalman CNPS-9700 and all the other competition for over-clockability through lower temperatures and narrower temperature ranges.

I'll sell you an Ultra 120 (original) for an "offer-you-can't-refuse" price, and you can put your Zalman 9700 on EBay.

 

[BonzaiDuck]

Oh. One more thing. As you can see, I'm in a bit of snit today -- waiting for the nice, cool marine-layer to lift so the sun starts baking my roof again.

So I'm making a bold pronouncement, to see what terse replies I get.

OC'ing the CPU to the max is not the most optimal solution to building a "fast" computer. If you can get the memory latencies down to levels like 3,4,4,6, you squeeze the same memory bandwidth out of the system that you'd have by running up your power bill a tad, stressing your processor and mobo, and forcing you into a cooling quandary with looser timings.

I believe there is a balance, and that you can get the same performance with a less extreme CPU over-clocking if you pay attention to bottlenecks farther down the storage pyramid -- like memory and hard-disk throughput.

 

[MarcVenice]

Theres a balance, but the general rule of thumb is that cpu speed is more important then memory speeds. And I dunno, you won't be doing 3-4-4-6 on ddr800, if his multi is at 9, and his fsb at 400, his ram will do 4-4-4-15, which is stock, and should be just fine.

And yeah, the ultra 120 or tuniq tower 120 will both cool his cpu better then his zalman, with 6 case fans he isn't exactly going for a quiet pc, so yeah. Using as5 or any silver compound might help a few degrees as well. I think getting past 3.6 really needs water though ...

*sigh* i need the guys over at a forum to sticky a basic questionair when asking these questions.

1. You did a good job at getting ambients. However this doesnt apply here. We need the ambients INSIDE your case. If you cant get the ambients inside the case, we need you to redue the tests with the SIDE PANNEL off, and ON to see if theres a large delta inside and otuside your system.

2. You failed to note what temp program you used. Did you use Coretemp? Everest? SpeedFan? Please dont tell me your using NV Monitor. Its VERY VERY INACCURATE.

Look at NVmonitor vs Coretemp. Coretemps is actually the more important program we need to look at.

3. I compliment you for giving your voltages out and also your difference in load temps vs idle.



Lastly, if you think your cpu has a heat problem, then lap the CPU. You will gain about 7-10C on coretemp by doing this. Your HSF might need a good lap job as well.

And incase your worried about voiding your warrenty, You already did it by overclocking, and using an aftermarket heat sink. And no you cant send intel a brandnew heat sink when you rma your 1yr old chip.



But i would do the side open pannel test first to see how much lower your temps will drop. If it doesnt drop at all, then your inside ambients and outside are pretty close to each other. That means your probably on the best your aircooler can do. Then if your not happy, lap the sucker. That should shave off a few temps from your loads.

But initally looking, your under the 70C max load temp everyone decided on. It was stated by most of the pro's on this forum, as well as others, that 70C below is acceptable for load temps. I personally dont like anything above 60C, but its personal taste.

So you follow under the -70C rule. So your temps arent anything to freak out about.

PS. Im on a high class water, so please dont try to mimic my temps. Its impossible on AIR.
