Another Q6600 Temp Thread - Need Help Please

[aheschel]

Wow,

Just jumped to Anadtech and have read most of the posts on the Q6600 (B3) and heat and I seem to be near Tahiti compared to everyone else. Just got a new rig using a 680i motherboard and a q6600. I have the Koolance (PC3-726SL, http://www.koolance.com/shop/p...28_43&products_id=186) kit and their CPU-330 (http://www.koolance.com/shop/p...29_44&products_id=402) CPU block using 10mm tubing. This kit has worked great in the past but my CPU is turning into lava now. Here are some core temp numbers
No Over Clock - 1.24 volts
: 0x6F7
Processor: Intel Core 2 Quad Q6600 (Kentsfield)
Revision: B3
CPU Speed CPU#0 (Core#0) CPU#0 (Core#1) CPU#0 (Core#2) CPU#0 (Core#3)
2400.00 60 61 62 60

2400.01 78 77 74 75

OverClock 1334 FSB (3.01 GHZ - 1.288 Volts Stable)
CPU Speed CPU#0 (Core#0) CPU#0 (Core#1) CPU#0 (Core#2) CPU#0 (Core#3)
3001.60 61 61 57 58

3001.60 81 80 79 80

These temps seem out of control and tried everything. I initially though I was setting the CPU poorly but reset it and same results.
Does anyone have any good links to step by step instruction for setting a water block and thermal paste? Want to make sure I am not doing something stupid that I forgot.

The CPU voltage is also takes a huge dive when I fire up Orthos on all 4 cores, like ~.4-.5. Is this common? I am using an enermax liberty (640W) power supply with some relatively nice hardware but should be fine for 640W (in signature). Is a bigger power supply needed or is this common on the 680i chipset.

Any suggestions to lower these temperatures would be a great help. They seem way too high for me for the decent water-cooling kit I am using.


Thanks,

Core temp may be reading 15c high ..
If it is, that would make your temps more realistic.. What is your CPU ( IHS )
temp, as reported by something like Sandra or PC Wizard ?

Some other consideration:
- All new hardware
- Let Artic Silver set for 1-12 hours before I turned it on for the first time
- When I did remove the water block the first time after setting; on the water block the contact seemed uneven with the CPU. Basically there was not and even amount of thermal paste on the bottom of the water block but there was the outline of the CPU. Thus I really thought nothing of it.
- Under full load the 1.288 voltz in CPUz drops to ~1.24.
* The sensor attached to the water Block also only goes up to 42C from 38 under load. The block is also warm to hot to the touch but nothing like these numbers above. The sensor in the case (open air) reports 27c.

Quad chips have a tjunction of 100c. Speedfan uses a tjunction of 85c. It, therefore, read 15c low. Core Temp will give you accurate readings for the Quad chip. Adding 15 to your speed fan results doesn't sound too bad for a quad chip - they do run HOT though that is quite high for stock voltage.

I think your main problem is the Koolance water kit. They do not have a good reputation - about as good as a decent air cooling at best. The design of the water block is of crucial importance with a quad core.

I would either replace the Koolance with a decent water cooling system or go to a top quality air cooler.

What would you recommend for a good quad core waterblock. Had great results on my X2 witht this kit but I am trying a new water block from them that is a solid metal and copper unit (check the link above). This could be the problema ansd if there is a Known good block for quad cores I will try that out.

that voltage taking a dive when under load is common, it is called vdroop.

for example, my board has horrible vdroop. under load, my actual voltage tot he cpu drops a full .1 (im guessing you meant .04-.05)

if i have 1.4v in bios, under prime load it drops to 1.3v

at 3.2ghz at 1.35v under load i drop to 1.26v and it stays rock solid stable, a -.09v drop under load.

I have the Swiftech Apogee GTX bowed which is considered by many, including me , as being the best. The d-tek fuzion is just about as good for dual or quad core.

im debating on getting a tt ultra120-extreme now or saving money and getting a $250 dollar WC solution for my first wc ever. just running 1 loop for now for my quad, maybe adding a block for my GC later.

what do you think i should do? input is good.

Thanks for all the tips. I followed artic silvers instruction versus the old school grain of rice and smear the AS evenly across the CPU and the results are significant. Sounds like my Water block was not seated properly. CPU (0) AND (1) are around 64C under full load with Orthos and CPU (2) and CPU (3) are at 59C. Using Coretemp. Not sure if people are getting separate temps like that on their CPUs during it but I could imagine that this is common. Setting it again is a mixed bag at this point. Do people show some differences in the core temp between the 2 dual cores usually?

 

[genec57]

The difference you are seeing between cores 0 and 1 and 2, 3 are perfectly normal. Cores 0,1 always take the brunt of the load leading to a temp differential.
With a water block more suited to quad core you should see a further significant drop in temps.
