Speedfan Question

[jonnyGURU]

I might have answered my own questions, but...

Speedfan is sort of annoying with telling you what temps are what.

I'm using Asus A8N-SLI Deluxe.

"Temp1" is apparently the CPU. I figured this based on the fact that it's numbers matched what was being reported by Asus Ai Booster.

"CPU" seems to be the GPU. I figured this based on the fact that the reading is coming from I2CNvidia SMBus, there's two readings (one for each card?) and it went up drastically when 3DMark kicked in.

"Temp2" and "Local" seem to be ambient temperatures as reported by the motherboard and graphics card respectively. These temps seem to be always the same, so I just monitored one.

There's a reading called "core" being reported by "PCI", but under chip it's listed as "AMD K8." So I assume this is the Athlon 64's internal temperature probe. MI-Tazz was telling me the temp was REALLY high (it was) so I'm not going to use it for CPU temp, I'm going to use Temp1 as reported by the board.

Here's what I have so far.....

w/ CPU at 2400MHz, Ultra X-Wind (controlled by QFan @ 1600RPM) & stock GPU cooling while idle

CPU: 57C
GPU: 47C
Ambient: 43C

w/ CPU at 2400MHz, Ultra X-Wind (controlled by QFan @ 1600RPM) & stock GPU cooling under load

CPU: 60C
GPU: 72C
Ambient: 51C

w/ CPU at 2400MHz, Ultra X-Wind (at full RPM, 1939RPM) & stock GPU cooling while idle

CPU: 57C
GPU: 47C
Ambient: 41C

w/ CPU at 2400MHz, Ultra X-Wind (at full RPM, 1939RPM) & stock GPU cooling under load

CPU: 59C
GPU: 72C
Ambient: 50C

w/ CPU at 2600MHz, Ultra X-Wind (at full RPM, 1939RPM) & stock GPU cooling while idle

CPU: 57C
GPU: 47C
Ambient: 41C

w/ CPU at 2600MHz, Ultra X-Wind (at full RPM, 1939RPM) & stock GPU cooling under load

CPU: 61C
GPU: 74C
Ambient: 52C

FYI: The CPU is an Athlon64 4000+ @ 1.65V, w/ four sticks (512MB each) of Kingston HyperX (2GB total), two 7800GTX 512MB cards, in a YCC case (sam as Akasa Eclipse) with two 120MM fans (Globalwin Golf, spinning at 2000 RPM.) PSU is Ultra X-Pro EE 600W.

You do know that you can rename the readings in SpeedFan I assume...

Figuring out which is which in SpeedFan sucks.

Normally what I do when I first install it, I will fire up some CPU intense programs and try to force the temp to fluctuate. Normally the temp that changes the quickest is the CPU or NB.

Core = I think your right.

Mine doesn't show graphics card on either of my systems. I currently swapped this rig over to using Hmonitor. It seems to be working fine with the EVGA board and it too has the same issue. Guess which sensor is which.

Those temps don't look to bad right now. Your CPU is running 9 - 16 degrees higher than ambient which seems about right. Whats the room ambient temp?

CORRECT!

But you have to figure out what's what first. ;)

Whats the room ambient temp?

About 26 or 27C.

My wife doesn't let me turn the air down to where I like it. :D

[Tazz]

I would say those temps are about normal then.

[jonnyGURU]

Cool. And if anyone asks about clocking higher than 2600 MHz... Instalock! Even at only 40MHz more than my highest clock!

Temperature? No. Doesn't have enough time to heat up before it locks. Core voltage? Dunno... I'll give it a shot. ;)

What stepping (http://www.amdcompare.com/us-en/desktop/SideBySide.aspx?opn=ADA4000DKA5CF&opn=ADA4000DEP5AS&opn=ADA4000DAA5BN) is your CPU? Vcore 1.65V seems high, in worst case it should be 1.50V.
For my taste your temps are high, especially in idle. Try RMClock (http://cpu.rightmark.org/products/rmclock.shtml) instead CnQ (if you use it) to fine tune your FID/VID based on load.

If you don't trust SpeedFan's core temperature readings try Core Temp (http://www.thecoolest.zerobrains.com/CoreTemp/). I guess that diode temp is higher than socket temp by 10-15°C right?
So there are 2 possibilities:
- crappy sensors readings
- a problem with heatsink (it's hot? because at 61°C it should be very hot when you touch it).

For my AM2 X2 3800+ SpeedFan core temp, Core Temp and RMClock temp are the same and seems accurate (idle room temperature plus ~4-5°C, full-load room temperature plus ~18-19°C).

Well, 1.65V is high. Not sure why I thought it was 1.65V. Turns out that it's 1.58V. But when trying to get the CPU to run higher than 2600 MHz, even with 1.65V, it locks instantly. I don't think it's temps because it locks as soon as I change the bus. There's probably something on the board that doesn't like the 220 MHz FSB. :D

Try to raise voltage (in small steps, and one by one) on NB, HTT, MEM and of course lower HTT multiplier from 5 to 4 or even 3.

Yeah, I too had to load the cpu's to figure out what was what in speedfan. I believe my speedfan shows 3 "fan 1"
