Getting pretty high temps on my Q9650 idle is in the 40/42/42/43 max load 72/72/76/74 vcore is 1.38v (cpu-z)
even at stock 3ghz with 1.2v temps are 39/37/43/39 max load 56/52/52/52
Could it be the fact I have the Block to tight or not tight enough.
I put a grain of rice size in middle, also tried spreading it over, maybee I have too much on there.
Using realtemp 3 to monitor havn't changed TJ Max left as standard.
Is there a diagram of the actual size grain of TIM to apply, never had a problem before but getting it now.
My water consists of 120.3, 18w DDC, D-Tek v1 w/quad nozzle, 2xAsus Mosfet blocks, XPSC NB and dual bay rez so pretty much up there.

What water cooling kit are you using?

Have you checked the orientation of your block? Also make sure you have the inlet and outlet the right way round.

What are your load temps? Idle temps don't really matter too much.
 
Vid 1.2500v
CPU-Z vcore idle 1.38v load 1.34v thats at 445X9 4002mhz same case as you.
Orientation is right, all I can think of is too much TIM is applied or the block is not tight enough or is too tight.

reseated it twice now, still the same. will have one more go later with a smaller grain size of TIM.
 
I know you've reseated but it does sound like a duff contact really. My old q9450 (C1) ran 3.6ghz on 1.264v under 100% load (1.33v in BIOS - 1.295v in wondows) and never went above 53c.

Cooling was provided by a Thermochill PA120.2, 10w DDC, an XSPC Edge and the thermal paste was Arctic Ceramique. The northbridge of my old Gigabyte X38-DS5 was in the loop too.

Also, the chip was not lapped.

Spec in sig, got CPU, nb and gpu under a PA120.3 with same pump and v2 block and get 60-65c load

Something is up ..

You are in a very similar situation to me at the moment both with temps and hardware. With using a D-Tek v1, 10w DDC, VGA block, XSPC RX360 and the q9650 at 1.34 my load temperatures(prime95) are about 8 - 10 degrees cooler although feel it should be a bit better than that at that voltage. On Intel Burn Test my temps are very similar to your load temps there.

Anyway...I've taken the day off so I can rip out the loop, clean and reseat everything again so I'll let you know if I see any change in temps. I'm going to put a backplate on the D-Tek v1 as well...have the one from my old Noctua cooler still kicking about.

I understand it's not exactly an identical set up with what we're cooling but there are anough similarites in hardware for me to hopefully give you a better idea of temps and any changes i make for it to provide some help or comparison. I'll let you know how I go on with it.

Sounds like your pump doesnt have enough pressure to drive that loop u can swap the wires to make it 18w i believe

To the OP sounds like you have air in your system.

I was considering doing this after seeing someone here post about it. I wasn't sure if I'd really see a big difference temps wise or not. If you think it would make a difference then I might give it a go.
 
If you want to make your pump into an Ultra you'll have to do a small bit of soldering.

Just need to connect those two places with solder.
 
I will give that rad a rattle see if there is any trapped air in system, highest point in loop is the Dual bay rez, which I think is how it should be.
Have given rad a good shake was some air, but only small amount. will try for re-seat again with very small amount of paste.

So does that mean you can turn an 18w into a 10w by removing the solder?

Mind I have reduced the voltage on my 18w and it silent now anyway.
 
Take a photo of the top of the IHS and the bottom of the block so we can see the contact marks. Before cleaning off the TIM of course.

well a vga block and a fairly restrictive cpud block i would recon so, waht vga block are you using.

The VGA block is the XSPC Razor 4870.


N19h7m4r3, thanks for the photo there.


Soldering iron is ordered now and am definitely going to give this a go. Cheers for the pointers folks and sorry for the partial hijack of the thread there, OP.
