P775DM3-G Overheating Woes

Are these normal readings?

No undervolt + repaste + Delidded CPU (The throttle drop was from lowering the voltage under load)

Undervolt + Repaste + Delidded CPU

Just for giggles I popped it in my desktop and chilled along at 65c 100% load. So I think I can safely eliminate my delid being the issue

Here's pics from my repaste. I used Gelid Extreme and Arctic's Articleaner kit as I usually do.

Could this be a defective heatsink? I'm really at a loss here...

 

I'm going to jump in to a Mass Effect Andromeda session and record the temps there as well. Will post if needed

 

Ouch 94c max on cpu 91 max gpu this is with undervolt

 

Your heatsink looks a bit furry. You cleaned that up right?

What did you use under the IHS when you delidded?
Edit: nvm saw you tested it in desky (WC/AIO could still hide a mildly dodgy delidding pasting mind you IMO if you're going to do it use liquid metal)

Those kinds of temps are not right for a proper delid. You'd expect thermal throttle in AVX stress from the factory. Not with good paste and a delid. Your paste job looks ok too so that's not the issue.

Any air gaps around the grill/fan join?

I just noticed you have the GPU box checked. Are the temps.similar when you're not loading up the GPU and adding heat to CPU over the shared heatpipes?

 

What is your undervolt value?

Here´s my results:


Notice it is @ 4.5Ghz + GTX 1080 @ 100% usage, OVERCLOCK fan profile.
Max temp is around 92ºC and not what you see in TS.

At 4.2GHz (which is your clock, you should stay around 85ºC)

 

I used Liquid Ultra for the IHS

There is a gap but it came that way from the factory. It's covered by a black plastic adhesive flap. I noticed a blue liquid when wiping down the heatsink... makes me think I've got a leak somewhere. Couldn't get a picture of it

CPU runs fine when stressed by itself. Right around 66c-70c. And yes I de-furried the heatsink lol.

I'm running at 4.2 with a -150mv undervolt cache and core. When there's no GPU load I hit a max of 70c

 

I would suggest using a line down the center on the GPU, and not using a line on the CPU, but rather the X/cross application method. The spread from the mounting pressure doesn't look good in those pictures. Have you noticed a big difference between cores on the CPU?

 

Not really. Usually within 2-5c from eachother. I don't personally think that the issue is with the paste. Definitely not after my last job.

 

If possible, next time you take the heat sink off take pictures of both - the heat sink and the contact surfaces. Will help in diagnosing the issue much faster.

For now I would suggest not using CLU if you know there is a gap.

 

Sorry? What is CLU?

And the only gap is between the heatsink and fan. But when I get home later tonight I will repaste (again) and take pictures of the spread.

 

The P775DMx runs a little hot no matter how good the application is. Still worth a shot if you have paste to spare.

 

Coollaboratory Liquid Ultra.

I think I misunderstood, that you used Liquid ultra on top of the IHS. And the gap was between the IHS and heatsink.
From the looks of the images , feels like the contact is pretty decent . Might actually be a defective heatsink. But the only way to confirm that is to try a replacement .

 

Reached out to Xotic and they re-directed me to Sager. Email sent off to them. @Meaker@Sager can you advise?

 

If you start the machine up are all the heatpipes getting hot equally fast?

 

Wont be able to check until tonight. I already have a new heatsink on the way from Sager so we'll see. But I'll get back to you on the heatpipe thing tonight

 

Welp the replacement heatsink did the trick. Chilling along at 76c with overclock

 

Clevo really need tot fix their heatsink QC lol!

 

Or Foxconn does.

 

Dont think Foxconn is still doing the heatsinks for them. I remember seeing another name on the DM3 heat sinks.
