(Aurora) R4 ... i7 3820 cpu.

 

1. between 38-44 C as the idle temps

 

2. and running bf3 something that requires a lot from the cpu the cores would run at around 60 - 68 C.

something up with my chip, or am I possibly (hopefully) just looking at a cooling issue? 

 
Yes, lines 1,2 are normal.
 
If now idle-ing at 83c, that sounds like a Asetek unit cooling problem. If MIO-Board was keeping rpms high then (instead of more normal 1500rpm) then that means it's working (trying to cool things down).
 
I think this applies:
 
 
Are you under warranty?

Everything with the core performance seems fine, but under load the system fan shoot up to 1800+ rpm. I think I still have about a month left on the warranty so I'll call to get a replacement organized.

Edit:

Ok now something really seems off. Just looking through everything with HW monitor again and it says all 3 of my system fans are running between 63-67% and I can't get anything to change them. The readings I'm getting for the Temperatures and Voltages seem way out too, such as my +12V reading 16.368V.... That's new...

If not already monitoring this, Install this to easily see CPU core load:

No, I meant something using CPU cycles when the PC is thought to be idle.

2. but under load the system fan shoot up to 1800+ rpm.

My notes:

Don't see them right now ... will post later.

But 1800 rpm under load is normal/fine (as long as temp stays under 70c)

My notes:

Watch it do this at Idle: Fan speed around 1200 rpm and 44c cores
 
While running Prime95 (cores to 100%), watch it do this:
 
Fan speed goes faster to keep the CPU cool ... as high as 2200 rpm, but no single core gets much hotter than 65c (maybe around 75c on 2nd and 3rd gen i7).
 
Stop running Prime95 after a few minutes (back to Idle)
 
Fan speed slows to 1200rpm and cores drop down to around 44c
 
If yes on the above ... the Asetek cooler and the MIO-Board and Command Center software controlling it is working (tests good).

Another Aurora R4 user reported similar.

Maybe someone with a working R4 can verify or let CPU-ID devs know.

CPU-ID HW-Monitor v1.21.0 (Driver 136)

On Aurora R1 (x58 chipset) and Intel i7-930

Everything (voltages, temps, etc) looks good EXCEPT:
TMPIN0-2 - Not sure which sensors they are.
Fans PWM - All 4 say 100% which is incorrect. Read these in Thermal Controller instead

Notes:
FANIN0 is Asetek radiator fan (aka System Fan)

I'll run the prime95 test when I get a chance later today. When the PC's idle a single core rarely goes over 3-4%t. I'll watch what the CC says the system fan is doing too, it just seems to be working a lot harder and I'm getting higher temperatures than usual when it's under load.

1. Good
 
2. Good
 
3. Right. So once you verify all systems are working (adjusting per. thermal-load) ... if all temps are higher then the Asetek unit might be going bad, became lose (not up against CPU properly), or some other similar problem.
 
Move on this is warranty is expiring soon.

Sounds like the cooling system as a whole is working. Maybe not as efficiently as you would hope or maybe something is broken. It's hard to say because I don't have that machine or processor. Prime95 is worst-case max. No game will do that (all cores at 100%) but video encodes and similar tasks will.

Is your system factory over-clocked ?

TJMax is around 100c, but 85c is still pretty hot. Seems like the rad-fan should go even faster (I thought max was 4000rpm) to keep temps under 75c. Obviously, the motherboard thinks that 85c is ok. Maybe Dell needs to adjust those numbers in BIOS?

Just did the Prime95 test, I think it must be the cooling unit. Starting with the cores 43 C, with Prime95 running the system fan gets to 2450 RPM, with core 1 and 2 at 75 C and cores 3 and 4 at 82-84 C with the package around 84 C, and it hit those temperatures almost right away. It's come back down to 45 C since stopping the test.

I just tried running BF3 to see what kind of readings I would get in the command center and they're throwing me for a loop. The HD fan said 0% but 4100 rpm, and the system fan sounded like it was running a lot but only showed 1900-2000 RPM. The temps dropped back to 50 C and the fans sounded more quiet, I relaunched the command center and it said the system fan was at 4100 RPM before refreshing back to 1200.

Tried the same thing with HW Monitor running this time and it showed the system fan running steady at 2100-2200 rpm, it seems like the CC locks up when bf3 was running or something. The temperatures are holding, a bit higher than usual, but staying under 80 C for the package. I was thinking that the CPU cooling unit was going to be my next upgrade, maybe something along these lines..

From the Intel site the TJMax on 2nd gen i7's is 105 C. The highest the fan hit was 2290 rpm when the package hit 82 C and it still hasn't cooled down below 50 after 15 minutes. I had used the overclock settings before but set it back to default just before the incident where all 4 cores were over 80 C.
