crazy Q6600 CPU temperatures

[ruthlesset]

I just together my system. When it boots up the CPU temp is around 30C. When I run prime95 the temp goes to 55C. Please note that I have not overclocked the system (and plan on doing so). The bios settings are on default. I am using Artic Silver 5 and have applied it according to the instruction on the artic silver website.

What is causing the temperature to rise so much? Is this normal?

My fan (Scythe SFF21F) has 1600CFM but the bios shows around 1506CFM.

CPU: Q6600 FSB1066 G0 (SLACR) (planning on OCing to 3.2GHz)
Motherboard: ASUS P5K-E/WIFI-AP (P35 chipset)
RAM: Corsair 2x1GB DDR2 800Mhz
Graphics card: EVGA 640-P2-N821-AR GeForce 8800GTS 640MB
Heatsink: Thermalright Ultima 90
Heatsink Fan: Scythe SFF21F. Fluid bearings, silent, 1600RPM, 63CFM
HDD: WD5000AAKS 500GB, 16MB cache (already have. $130) and 2 SATA 160GB Seagate HDD's.
Optical Drives: one DVDRW and one CDRW
Sound: Audigy2 ZX Platinum
ENERMAX Whisper II EG465P-VE FMA 1.3 ATX 460W Power Supply

Any help is appreciated.

Thats 1506RPM, rather then CFM.

I use thermalright ultima-90 too and at 1.3vcore and 3ghz, I get idle temps of 30 - 35 and load temps of 40 - 50. Hardly ever goes above 50 though.

In BIOS its probably just set to auto which usually just puts things high, anything up to 65-70 degrees is acceptable though. Your temps are pretty gd.

 

[ruthlesset]

you are right... its 1506RPM.

How do I get the RPM to 16000RPM or make sure the temp does not go above 50? I am scared of opening Quake wars demo, because the temp hits 55. Please note I put together this system yesterday and have not overclocked it yet.

Make sure your ATX Case is properly ventilated. You should have some intake fans and some exhaust fans. Also make sure that there's good air ciculation within the case. Tie up all those loose wires and push them off to one side. And the fans should be oriented in a way that gives incoming air (from intake fans) a direct path to exhaust fans.

I'm using a mid-size ATX case, a pair of 80mm fans exhaust fans at the rear, plus the PSU exhaust fan, a 80mm intake fan on the side panel, a 120mm low-speed fan in the front panel, plus a Zalman 9700 CPU cooler.

Q6600 SLACR 333mhz x 9 = 3.0 GHz @ 1.275v
Idle temperature: 37 degrees @ 60% fan speed
4 Cores Fully loaded via Orthos: 50 degrees @ 100% fan speed

Wait a week for the AS5 to settle on your CPU before you take your temps too seriously. Its running at decent temps already.

I have my Q6600 OC'd to 3.2 Ghz and it runs around 30-32C idle, 52-58C under load from Prime95. Think my VCORE is around 1.325 or so.

Rather then that, heat it up then shut it off for a bit then repeat.

Seriously 55degrees.. don't worry about that at all.

I dont understand why you put artic silver on it, when the fan came with a sticky pad of thermal past on it!... Unless u installed your own cooling.........

Regardless there were problems with people last year, when the first C2D's came out, and people were applying themal past to the CPU when they didnt need to because the fan that intel supplied had paste already on it... 2 pastes = ftl.

Thanks for all your replies. Well my case has 6 case fans (3 intake and 3 exhaust) + 2 PSU fans (which blow out air). I have also kept my case open just incase I need to move something inside.

Also I am using Thermalright Ultima-90 and bought the artic silver 5 for it.

I have overclocked my CPU to 3.0Ghz with the vCore set to 1.265. But Asus probe II shows the vcore as 1.21. Any idea why is it happening?
Please note: I have manually set the voltages only for vcore (1.265v) and (dram 2.1v). All the other voltages are set at auto. Also FSB is 333 and PCIe is 100 and dram is 667Mhz and cpuz shows the timing as 1:1.

It now idles at around 35-40 and when I ran Prime95 it hit 70C (I use core temp and speedfan) in 20 mins after which I stopped Prime95. The system was on for 24 hours and was stable. I played HL2 at full settings and the temperature was around 52. I need to install and try FEAR and C&C.

there isn't much point to having the case open with all thoes fans running. all you are doing is messing with the airflow. with your temps its nothing to worry about at this point though. my q6600 runs at 65 when under load.

My Ultima90 came with a tube of thermal paste and didnt have any applied to the heatsink when it arrived, so IDK if yours is the same as that.

Still, you're being a bit paranoid its completly safe to go up to 70degrees without worrying. You're well within the limit.
A lot of boards set eh actual vcore as lower then what you put, dw about it, also put less voltage to your memory, 2.1volts is a bit excessive.

1.21vcore for 3ghz.. thats actually pretty awesome. I need 1.3volts for 3ghz.
