Q6600 at 80c load? Help!

[s2kpacifist]

I'm not sure what's going on but I just made a new system and the g0 q6600 at stock speeds is running at 80c load under prime95. 70-75c with bioshock maxed out.

I reseated the cpu and heatsink but it's reading the same temps.

Right now the comp is idling at 55-60c. I'd say the average is about 65 on normal use, and in prime95 no errors or reboots. I even set a cpu warning for 80c and it didn't trip, strangely enough.

The cooler is a zerotherm cf900 with arctic silver 5. I've built dozens of comps before I'm quite sure I didn't do something stupid. Coretemp 0.95.4 was used to get the readings.

The case itself is a mATX with only one large intake, but I doubt it would have that big of an effect on the temps. Something's off here ><

Why not say exactly what case you're using?

In any case, that doesn't look like a great cooler to be using, especially on a quad. In fact, I wouldn't really recommend running a quad in an mATX case unless you absolutely need and can use all 4 cores. And in that case, you're gonna need much better cooling. An XP-120, NT-06, or Zalman 7700 or 8700 would probably perform a little better.

Basically, I don't think anything is off. Instead, I think you just need better cooling. Those temps sound about right to me, especially with that cooler. Doesn't look much bigger or better than the stock Intel cooler.

what he said

Whew thanks for the reply.

Ah sorry, it's a silverstone SG03 (new version). The power supply is sitting right above the CPU fan which unfortunately limits the size of the heatsink/fans i can use.

I do use all 4 cores btw

That xp-120 and nt-06 look good, but I don't think i can fit a zalman into the case. I guess I'll make a trip to the shops and pick up another 120mm front intake, and one of those heatsinks. Thank you for your replies

Also there seems to be a 5.25 mount bracket in the back of the case...I may add a 5.25 outtake fan to push some air. Any recommendations on one?

 

[Trevante]

Get the NT06. Which PSU do you have? The NT06 + PSU Fan should work well, although it still may not be enough for a quad. Get as many fans in as you can.

And thank you for using all of your CPU cores:thumbsup: I hate it when I see people who want to get a quad just because they're cheap(er) and don't need the extra cores, yet wonder why their systems are so hot.

Can't remember what the name of thread was, but I think someone on Hardforum had pics of his SG-03 with the extra slot cooler at the top (I believe that's the 5.25" bay you're talking about right?). I don't remember what kind it was, but I think Silverstone does make their own brand that should fit right in.

will the Thermalright Ultima-90 fit? It's alow smaller than the Ultra-120.

A nice mATX case, but upping the airflow is a must. This things not suited for cooling a quad.

The front panel will accomodate two 120mm fans:

The 120mm fan located behind the grill is installed in the middle, but depending on the user's cooling needs and system setup, it can be moved up or down on the grill in order to make room for a second 120mm intake fan. The included fan has a 4 pin molex connector for power and a smaller 3 pin connector to monitor /control fan speed.

You're gonna need two fans in front, high speed (2000 RPM), a slot or 5.25 bay cooler may be necessary too. Better CPU cooler as suggested.

I'd say that's normal. My q6600 with open case was reaching 79C, and probably higher. It's running at 73-74C under load with 4 instances of prime once I close the case and installed fan.

I'm using stock cooler right now, complete with crappy thermal tape instead of paste.

 

[s2kpacifist]

Sounds good. I'll be picking up a FX121 crossflow fan from silverstone and another 120mm intake tomorrow. Let's see if it'll cool the beast

 

[s2kpacifist]

Wow what a difference! It's lowered the temps across all four cores by more than 10c. Load on prime05 running for an hour is 69C, as opposed to the 81C. It's idling at about 46C, very acceptable for a cramped mATX

The FX121 crossflow fan i bought today barely squeezed into the case, and that's with the somewhat small aeroflow CF900 there. There's about 2mm inbetween the fan and the mounted crossflow fan.

Didn't have any trouble installing the extra 120mm fan, and the noise increase is barely heard.

Very happy, thanks to everyone who posted

im not sure if ive stumbled onto anything but have a read anyway.

ok ive got the Q6600 G0 on the Gigabyte P35C-DS3R Rev 1.1.

my temps used to be pretty high and ive been playing about, i found that the G0 stepping run on a Vcore of between 1.1 and 1.3, so i ran CPU-Z and its showed my Vcore was at 1.27.

temps @ Vcore 1.27

Idle 35-40
load 60-65

So i manually set my Vcore to 1.1

Idle 18-24
load 40-44

This is at stock 2.4Ghz with memory at 1:1
Speed stepping enabled so when idle cpu is @ 1.6Ghz.

if i set my Vcore to normal in the my bios it sets it to a 1.3 if i set it to auto it sets it a litte higher, So download CPU-Z and check your Vcore.

Oh and ive just ran prime95 on all 4 cores for 12hours and its 100% stable so far.

 

[s2kpacifist]

The voltage bounces between 1.12v and 1.2v in cpuz. That sounds about right, I think.

Yeah but try and get it down to 1.1 in CPU-Z and then check your temps you'll be suprised.

Glad it helped...

Okay so i messed around the G33M bios, apparently I'm having the opposite end from yours sniperdaws. By setting the vcore to 1.1 in bios, it's actually a lot lower (about 1.056 in cpuz) and strangely enough the temps are about the same. I had to set it to about 1.23 in BIOS to get 1.1.

I can hear the CF90 fan speeding up and down during the vcore changes, so the fan speed controller is keeping it at around the 45-52c mark, regardless of what the vcore is. I may have seen changes if it wasn't a temp controlled fan, but I don't have one laying around atm ><.

 

[SniperDaws]

Yeah i meant set your Vcore so it reads 1.1 in CPU-Z but its strange that the temps havent dropped.

ive just noticed you are using CoreTemp, aparently its giving too higher readings with the G0 stepping, you can knock about 10 degree's off Coretemps readings.

Find out what your temps are like in your bios.

No, that's not true. Coretemp is correct.

 

[SniperDaws]

Well core temp is 15c higher than my bios and speedfan are reporting so maybe its just me then.

 

[SniperDaws]

oh well looks like im a complete knob and my cpu is cooking.......lol

im looking at getting a Scythe Ninja or Artic Freezer 7 which ones best cos this stock cooler is as like a chocolate fire gaurd.
