AW 15 R1 4710HQ high temps after repaste

Hi,
I own a AW 15 R1 (4710HQ, 970m). I have been following this forum ever since I bought my laptop and after seeing the repaste results here, I decided to repaste my AW (6 months back).
Previously I used to have severe throttling (800mhz). I used throttlestop to disable prochot97 and hwinfo to increase fan speed, but that wouldn't stop the temps from spiking. So I decided to do a repaste myself.
I used the noctua NT-H1 that was lying around from my previous build to repaste. It worked well for a couple of months, and even with stress test it wouldn't cross 85 degrees.
Recently, I started gaming again (mostly overwatch) and now the temperatures are constantly hitting 95-98 degrees and the cpu freq stays at 2.5Ghz at which point the fps drops severely and I literally can't play anymore.

Do I need to do a repaste again? If so, what paste is recommended? I live in India, TG Kryonaut is very expensive here and hard to get. Arctic silver 5 and Noctua nt-h1 are easily available. I didn't replace thermal pads last time, not sure if that would help. Also, this laptop doesn't seem to support checking the pch temp, can't find it in hwinfo. Any suggestions that would help lower the temps in this machine?

 

You should do a repaste again. Try Mastergel Maker Nano . NT-H1 is not really good and It wont last long. With good paste, It will never pass 75*C when gaming.

 

I just checked in amazon. Looks like kryonaut and maker nano are similarly priced. It's gonna take a couple of weeks for me to order and do the repaste. Would you also suggest replacing the thermal pads? I was thinking of arctic, since I wasn't sure if fujipoly is worth the extra money here.

 

i have the same specs and i managed to have really good temps. your problem is that you used a thermal paste that loose performance over time. you have to use something like IC diamond 7 that is a lot better. also you can make an undervolt using throllestop i use -60mv for core and cache

 

this is the correct product. I got it for 890₹. https://www.amazon.in/Cooler-Master...qid=1518972393&sr=8-2&keywords=mastergel+nano
Judal57 knows my PC better than me.

 

I'm gonna keep an eye on those prices. I'll do a repaste and get back to you guys with results in a few weeks time. Thanks for your suggestions

Hi guys, I finally opened up my laptop. Most of my previous paste noctua nt-h1 had gone (its operating temp is < 90 and mine consistently went above that). Repasted with Mastergel maker. I also added a thin copper shim for the pch. In balanced power mode and after 4 hours of intense overwatch gaming, temperature maxes out at 82 degrees (97 before repaste) and pch temperature hovers around 75 degrees (90 before repaste). Seems to work so far. I'm afraid to go for the high performance mode since it's gonna increase the temps obviously.

P.S: The ambient temperature at the time of testing was 38 deg C.

 

Before re-paste: Freq started at 3.3Ghz and immediately drops to 2.5Ghz due to throttling and occasionally to 1.8Ghz, temp at 94-97 degrees.
After Re-paste: The cpu frequency maintained at 3.3Ghz during the entire gaming session while the temps maxed at 82.



PCH temperature is also consistent and stays around 75 degrees.

 

Add 2-3 layers of 0.5mm arctic pads on PCH, RAM(single layer), SSDs like @judal57 did.
Temps are great almost good as mine. I use CPU performance mode now because my fan respond late in hot humid summer.

 

you are not making undervolt.. you could reduce temperatures a little bit more by making one

 

I used the same thermal paste to fit the copper shim and thermal pads on the side and at the top to hold it in place with the base structure. I'll add pads to ssd and ram.

 

Oh I almost forgot about it, thanks for reminding. Before repaste it used to crash even for -15mv, I wonder if it's gonna make a difference. I'm gonna try now. I'll let you know, it's gonna take a while to see if it's stable.

 

Disable hibernate or hybrid startup.

 

Yeah, I've disabled all of them. I also disabled express charge.

 

-15MV IS TOO LITTLE. use -50mv is safe

 

No what I meant is, before repaste it won't even let me go beyond -15mv - it would just crash. I have no idea why.

Last night I tried undervolting more. I was able to reach -60mv without crashing. It has been stable so far. Here are the temps after running OCCT for like a couple of hours.


When I started the test, temp went up to 85 before the fans started spinning and then the peak settled at 77 deg for the rest of testing. When I run throttlestop, I get warning to stop hwinfo. Not sure if I can run a custom fan table along with throttlestop.

So here's my final list of changes executed:
1. Repaste with Mastergel Maker
2. PCH mod with copper shim - Thermal paste between the pch and the shim and thermal pad on top to stick to the base plate.
3. Undervolt : -60mv
4. Power Options:
a. Mode - Balanced
b. Acoustic limit in Intel Dynamic Platform and Thermal Framework - 5
c. Hybrid startup and dell express charge disabled

Results:
Max CPU temp while gaming - 80 degrees
Max GPU temp - 60 degrees.
PCH temp - 75 degrees.

I am really satisfied with the results so far.

P.S: I'm using A09 bios, I read in this forum that A10 bios released recently caused some sluggishness, so I think I'll stick to A09 for now.

 

hi just wondering if you tried to slightly elevated the back of the laptop ang see temps? might help..

 

Yep, they're already elevated. But this is the AW15 model so the vents aren't extended like the newer models. So temps might be a couple of degrees high.

 

ahh ok..

 

Disable OCCT sensors and set it to disabled. Use HWINFO to monitor temps. OCCT simply spits out more CPU temps. Even AIDA6 with CPU,FPU,cache,GPU should do the trick.

 

So my -60mv undervolt crashed. I guess I'm unlucky with the chip lottery. :c
I'll use hwinfo for the temps and report. Since you said occt reports higher temps, I'm kinda happy inside.

 

Haswell can be a very mixed bag when it comes to undervolting. I have the same experiences as you with the same chip in various older laptops that I used. Barely could get an undervolt of 60mv at the highest.
