CPU Thermal Paste for Core i7 laptop

Hey guys, i just bought a new laptop and id like to repaste my CPU, the oem paste is trash so id like to redo it, my laptop is running a 7700HQ i was wondering if someone could tell me if Arctic MX-2 would make a difference compared oo the oem or if i need something better what do you guys recommend?

 

Arctic MX-will likely be better than stock paste. I used Kryonaut on mine and it is great, but some people here are reporting it is drying out needing a repaste after a while, not my experience though. Going on a full year with good temps. Phobya Nanogrease Extreme is being recommended now because of the higher viscosity, ideal for laptops with low pressure and uneven heatsinks, and very good thermal conductivity. I did try it, but Kryonaut worked better for me.

 

Ok great thanks man! I’ll see what my MX-2 does I’m just not sure cuz I don’t wanna open my laptop a bunch of times, would you know if repasting voids warranties??

 

MX-2 is complete garbage. It will dry out so fast it will be like using toothpaste for TIM. Ceramique2 is better, temps may be higher at first but at least it won't dry out so quickly.
Kryonaut is only good if heatsink pressure is even and strong. Imbalanced heatsink will make Kryonaut pump out.
Coolermaster Maker Nano is probably the best for weak heatsinks on laptops now. I recommend that. IC7 diamond is good but it can cause scratches and abrasion when wiping off, and that's not going to be fun if you ever want to switch to high end TIM someday (like liquid metal).

 

Ok that’s good to know thanks!! In my case, I’ve got a Nitro 5 I’d just like to have something that can last while giving me better temps.. I’m not to sure how the heat sink sits on it but I haven’t read anything about it sitting crooked.. so just really to bring down my temps and not to dry out, what would be the best option in that? Lol

 

check my signature

best non metal pastes atm are Kryonaut and GC Extreme

 

@Kiliano Cinelli You can look at this thread too. http://forum.notebookreview.com/thr...nd-apply-traditional-and-liquid-metal.806840/
See if you can acquire any thermal paste mentioned by @jaybee83 or me that fits your budget.
GC aka Gelid Extreme is the new affordable paste that lasts very long. I personally use CM maker gel nano since Kryonaut was priced close to 30-40$ for 1g and CM Maker Gel was costing 12$ for 10g and came it spatula and isopropyl prep pad.

 

Ok awesome thanks so much guys! I’m gonna read the posted link and check out the pricing for the those pastes, I’m going to try to get the best one that is reasonably priced for a small tube lol but the one mentioned above by vasudev that comes with the little kit to properly apply it sounds interesting. And all of these pastes can be used on my gpu as well right?

 

Even gelid extreme and kryonaut comes with applicator. You can order a box of alcohol prep pads from Online as well. I use 70% ispropyl alcohol.
Gelid, Kryonaut, Cooler Master Maker Gel Nano recommends you to apply a small dot and spread it with a thin layer for 100% performance and great reduction in temps.
This is my horrible repaste results, do read page 5 and 6.

Then I decided to repaste again, this time using very small dot and then applying another dot if necessary.

Ok thanks! I’m just worried about what everyone is say with the low pressure from laptop heat sinks and the stuff leaking out... I just want one with good temp reduction that won’t leak all over the place :/

 

icd7 better than mx-4, I only tasted those two

 

Tasted? Those are poisonous substances.

 

Bah, nothing beats the taste of liquid metal TiM. It's the taste that says "Take me to Valhalla and make sure the beer and Valkyrie wenches are waiting"

...Please don't actually eat/drink liquid metal.

 

LOOOL you guys are funny. What ICD7?

 

lol right tasted```````

My CPU i7 7700HQ is still overheating. I've repasted 4 times but still climbing to 96 C° on full load and while gaming. I think my 1070 graphics card is working the i7 to hard perhaps and it's just normal??

 

Lap the heatsink.

 

how did you apply the thermal paste? what was the spread like when taking off the heatsink? was the chip completely and evenly covered? same for the heatsink? what kind of "full load" are we talking about here, aside from gaming? 96C is definitely too high. u could always try undervolting if nothing else helps

 

What would I need to lap the heatsink?? Here is my heatsink...

 

I spread it thinly and then thickly, applied the dot method and then line but I'm still getting the same temps all in the different methods so I dont know if it's my heatsink...

 

Get 3m dry/wet sand paper with 800 grit and sand the heatsink twice in one direction.
You can apply single layer of 1mm pad on each side except in the middle. I think its creating a gap. Make sure you press the heatsink very firmly before screwing back everything. Don't apply the paste yet since you need to assess how the pressure is distributed. If you see uneven pressure or traces on pads reduce the size to 0.,5mm.

 

Use a single stroke to get clean thin layer. Use half pea at the top or at center then in a single stroke with a spatula you should get a thin layer. Which paste are you using?

 

What you mean by at the top? I've used TG 4 Thermalake and Noctua h1-t1

 

The second thinner thermal pad is what I meant. I forgot to quote correct post!

 

Must I try put thermal pads on either side of the CPU copper heatsink except where the thermal paste will make contact on the heatsink. Is it safe to keep the thermal paste on the copper? I see it will stop hot air and heat from getting to the paste and dry it up. Correct me if I'm wrong as I might have misunderstood

 

Also when you're finished, try this test I recommend to everyone.
Apply a VERY small thermal paste dot in the very center of the die. In fact you can do this right away without even doing ANYTHING else yet.
Make sure the CPU and heatsink are fully cleaned before doing this.

Apply a thermal paste sized dot the size of a pin head or heck, even smaller than a pin head. It MUST be a small dot. This is VERY Important. Applying too much will not show what I want.

Then tighten the heatsink down with the screws evenly in a criss-cross pattern, with partial turns diagonally each time. Please do small turns at a time. This is VERY IMPORTANT!!!
Then after fully tightening it, unscrew it, remove the heatsink and take a picture for us of the heatsink and the CPU please.

 

0.5mm to be put on the heatsink?

 

I will do. Thanks. I will post a picture

 

Will a pin head not be to small for the CPU i7 7700HQ?

 

Trust me. We're not going for complete coverage at all
it's just a pressure test. a spread test.

This was ivan's test for me.
From the picture you can see that the paste is collected more at the top than the bottom. So he had much higher core temps on cores #0 and #2 than #1 and #3.

 

Ok will do. Thanks so much.

 

Please check my last edit.

The paste outline marks correspond to the marks on the HS here.

 

I'm using Noctua h1-t1 paste. I will use thermalake tg4 to experiment with those tests above instead of using the better paste.

 

Alright. Will post two photos tomorrow of the CPU and heatsink when I do the pressure test

 

aaaaand ur spread actually looks pretty good. so id say go for undervolting

 

I used a pin size about dot for the pressure test. I have undervolted to 115 mV Core and Cache originally.

 

so wait, ure overheating even with that undervolt already applied? if thats the case, maybe one of your heatpipes got punctured and leaked...

 

Thank you. Your spread test looks flawless. Check the other replies.

 

Ok cool so there is nothing wrong with the pressure of my heatsink? Must I spread the paste evenly on the whole CPU now??

 

It's a newish computer so I cant say its leaked? How can I tell??

 

well one easy test would be to dip one end of the heatpipes into hot water and check if the other end gets hot immediately. if it does, ur heatpipes are fine. if it doesnt right away, its a sign that heat isnt being transferred efficiently....although that doesnt really happen all that often....

Stress test to come up

 

If you set your fans to the max with the Cooler Booster button, what are the temps?

 

I dont have that option. Its a HP Omen 17 GTX 1070 laptop. The fans only go to max when the laptop hits 90 C° when they kick in.

 

holy crap! high 90s at 44W package power!!!!

 

See this picture:

There must be performance mode in Advanced Section of ur BIOS. If there's one, enable the fan performance mode on Omen 17
