thermal paste Which Thermal Paste to buy and apply (Traditional and Liquid Metal)

[ryan]

ill just let this settle as you guys say it takes time to cure, i kinda lied lol well exaggerated ive only had it on for a day but my reasoning is why would it need to cure, makes no sense but you guys seem to know what your talking about....its been on for a day and a half but my temps are awful...oh well i hope your right..if they dont improve im trying LM

As long as its not thermal throttling in prime95 with maxed fans then it's considered ok.

 

If you want 80ish C with prime95 liquid metal is the only way to go.

I’m just going to say it: LM requires good heatsink contact, which is difficult to achieve on a laptop, plus special techniques to protect the electronics.

Difficult no, but nor is it guaranteed.

 

However most laptops can and do benefit from LM over paste.

 

Regarding LM leakage, it's only an issue if you apply too much or apply it like paste and expect it to spread itself. Even when you move it around a lot.

 

That said, having a extra layer of foam dam definitely helps give you peace of mind.

Compared with the desktop... I mean it must be relatively pretty poor - just compare the size of the fittings/bracket.

I would not bother with LM unless a non-conductive paste yielded reasonable results. Failing that, you'd know there is a heatsink problem and LM application is likely to be problematic and/or ineffective.

[ryan]

so what are my options?

 

Im not doing liquid metal

Im not trying a million laptop coolers but there has to be a way to either buy a SF19 somewhere, I dont trust the 20c drop with the Iets GT500 thats to much of a drop from just blowing air through the vents and at the pipes, maybe 5-10c with the bottom cover off.

I also swear by LM. On my Legion and AW17 both have had the best temps with LM.

Almost any other paste is OK, even satisfactory. But for pushing limits LM all the way.

My laptops are pretty much desk bound...not being transported much at all.

Those are both higher end machines which likely have decent heatsinks etc. Probably not the case with the machine discussed (HP Omen if I remember correctly).

@ryan

 

The only advice that springs to mind there is maybe apply normal paste, take the heatsink off and assess the fit. You should see a thin even layer of paste. If not then maybe think of some heatsink pressure mods or see if the screws could be tightened differently. Then again, all this bears the risk of stripping the screws. 
Actually, best advice would be to get a better laptop if possible. Clearly you are quite unhappy with this one.

I swear by LM on the cpu. Gpu you'll get by using any high end paste.

yeah its funny how CPUs somehow have a far higher thermal density and require much higher-end pastes / LM whereas GPUs with their insane TDPs are quite "happily chugging along" even with regular pastes.

What are your temps when running benchmark tests like Cinebench and when playing games. I think its your mixed capacity ram setup that causing the stuttering issues and/or your laptop heatsink isnt aligned property after the repaste. Also thermal throtting happens when the CPU hits around 95C and GPU temps hitting around 86C.

[ryan]

during cinebench its not the temps, it goes to 90c and stablizes around 85c but the clocks drop to a locked 3.4ghz

 

and @Etern4l yes im thinking of selling and doing an upgrade or just accept this laptop trash for what it is

oooh....might you be running into a power limit or CPU VRM throttling? sounds like your cpu temps DID actually improve, but now causing the cpu to hit its power limit or overheating the VRMs, in turn causing the downclock 😄

That too lol.

@ryanSorry for asking this, what's the voltage or VID shown by ThrottleStop or HWINFO for single and all cores usage while gaming or in compute intensive tasks?

Do you have latest uCode for your CPU? I remember Intel tweaking min/max VIDs via uCode to prevent Plundervolt or Cash-out exploits.

[ryan]

its varies, its not locked but it goes from 0.9 to 0.850

 

currently im just undervolting and temps seem in check. undervolting seems to be the solution.

 

side note while running stock clocks my system shut down due to overheating, so i guess ill have to undervolt and lock fps to 60 to avoid overheating until i get the courage to apply LM. funny how when im just benchmarking temps are fine but when i want to play a game its  shutting down due to temps.

I'm guessing you don't need me to tell you you need a repaste ASAP

[Etern4l]

Yeah, random shutdowns are really bad. Is a screw missing somewhere?

Voltage seems to be okay but low and feels more like idle state.

Is Intel MEI FW and BIOS up-to-date?

LM will not magically bring the CPU temps down if the heatsink is warped/flawed. Also make sure Windows doesn't update your BIOS, more often it installs wrong EC and BIOS meant for older device id/model. Ideally disable BIOS upgrade from  Wndows update in BIOS settings.

[ryan]

I now just lock framerate to 60 and run 3.9 ghz with a gpu undervolt seems to stay in the 60s-low 70s

I ordered Honeywell 7950 pads (40x80) last thursday from ebuy7 as i ran out of the paste version. I was going to order the ones from Amazon but they also come from China so it'll take the same amount of time to get here anyways. Personally i would recommend only buying it from Ebuy7 so you'll get the real deal for sure.

I might buy the gt500 its only 100 bucks, well worth it if the claims are true. i'd be happy with a 5-10c drop. as for the pads I think after a while and once they set they are king but don't expect a 20c drop in max temps. I think my next step is sell this thing and get a desktop(maybe). only problem with desktops is the gfx cards are hella expensive, 2300 cad for a 4090, sure you get more performance but doesn't seem worth it unless you are well off.

I think you should try the repaste again because something isnt right, Maybe with real thing or something else. The random shutdowns can also be caused by a too low of a undervolt.

 

Yea the 40 Series GPUs are overpriced as hell. If you do build a desktop go with a 30 series GPU if you can. There are some decent deals for them even for the RTX 3080 and even RTX 3090

funny how the highest / best value card of the 40 series is the 4090 😄

There is nothing funny about how Nvidia has been treating consumers lately.
