Which thermal paste should I buy?

Oh yes, the method for which you paste has great impact, combined with the type of paste, leads to a drastic difference.

I've learned that with my newest laptop.

 

i still wait for my paste.I ordered it two weeks ago and the seller acts like i didnt so i order it from ebay.Im really pissed off by that.Btw on one fan notebooks does the fan cool the cpu or gpu?

 

Both.

 

you know why i asked that?cause my cpu temps always raised proportionally with gpu temps and it always stayed below 80C.Now my gpu temp have increased 6-7C more than last summer which ofc resulted with 6-7C increase in cpu temps also.I thought the fan is broken but when i put my hand left i feel warm air.So i guess fan works properly?its just cause of thermal paste and dust?

 

Most likely due to dust, as well as thermal grease deteriorates. Remember that CPU and GPU share heatsink, heat pipes and fan.

 

I've found that using a cooling pad helps reduce dust within the laptop. It seems the dust becomes trapped in the pad first, then whatever is left moves on to the laptop. I'd say there's at least 80% - 90% of the dust piling up on the cooling pad, considering how much I've encountered this past month of ownership.

Just some fruit for thought. If you use your laptop at a desk most of the time like I do, then it will be beneficial.

 

As long as you using fan filters.

 

Aren't those fan filters going to get filled with dust and eventually get blocked? I noticed a layer of dust on my fan filters today, and I don't plan on disassembling my notebook anytime soon.

 

Disassemble and clean the fan filters on my Cooler Master U3 with mod 12v fans takes less than 2 min. Much easier than cleaning the fans and heatsink in the laptop .

 

i am getting temps spikes. is that a problem?

 

No problem if you are getting CPU utilization spikes ... for example if the utilization shoots up to 60-90% on a certain core your temp should shoot for 55-70c and then drops back it is normal

 

I have the laptop in my sig (NP9377sm-a) I am wondering if installing sometime like http://www.ebay.com/itm/Black-Dustp...896?pt=LH_DefaultDomain_0&hash=item5d5738a640 would be worth it and would this impead the fans ability to cool ? thanks

 

Hello mate,
I'd say get a CM notepal U3 Plus and install custom fans (DT ones, high cfm) & use nylon stockings as a filter, a friend ( @Papusan) did that and pretty neat and effective
Here check this page on U3 thread

Can also use this Bitfenix Fan controller too for controlling fans (Replacing the U3 ones because they are small and low CFM)

Spoiler

Oh, about those 80mm fans I guess you are right..!

Well that PSU link doesn't work...

 

What do I need a laptop cooler for? And why use diff fans on it than what it comes with? Custom fans ? What's DT & cfm? Sry for so man questions lol

Well, My point was.. I thought you want to cool your machine off efficiently so I posted that u3 mod for ya, & Custom (U3 stock fans are puny with beast machines that we have so replacing them) DT fans = Desktop Fans (high CFM - more air flow rate).

You can opt for it if you can do the stuff with U3

 

These fan filters seems to have too much plastic, which stops the air flow... Used nylon stockings as a filter is much better and is free as my Wife have used them

It's brilliant because you almost never need to clean the fans and heatsink in your laptop. I clean my laptop fans and heatsink only every 5 month now and almost no dust in my laptop when I start cleaning.

 

Ah yah I think you must have read someone else's post I was just asking if the fan filters I linkd would work on my laptop and if they do would they impede the air flow heh I actually have the cm sf-19 but I really have no need for it but it came free with my laptop along with an extra 120hz display and edp cable (which I am too scared to install)

Yah I am just mostly looking for in the future because right now I have to clean the fans/heatsinks every month to keep the warranty valid so don't really need a filter now since I clean every month anyways but after my warranty is up I will deff take ur suggestion

GC Extreme, IC Diamond, or on the extreme side Liquid Ultra. These threads always end the same. If you need a reliable paste, you go to one of those three. If you can't access those, and you can follow directions, Arctic Silver 5 is everywhere. Nothing else is acceptable for laptops. These things have been tested. What works great for a high pressure desktop mount doesn't work the same in a low pressure mount.

ShinEtsu X7921 is great too... But even less accessible than the others...

 

After 1 month of using Zalman stg-2, not sure if it's caused by the thermal paste

the cpu temps is 100C in GTA 5 and 90 C for the gpu

what makes it worse is the laptop has one very small stripped screw and i can't clean nor repaste.

wonder what made them choose such cheap screws? I have seen quite a few people who have had this same exact problem and their screws are stripped sorry about your luck hope you get it fixed soon!

 

You mean the head is stripped and you can't remove it or the screw itself won't tighten fully due to the threads being stripped?

If it's the head of the screw and it's a Torx, try jamming a flat head across it or using a rubber band..

 

Didn't work

geez what did you do to the area all around it?

 

the most stupid thing i've ever made in my entire life, trying to remove the screw by drilling
and by using super glue.

 

If you have access to a dremel, make a slot in the top so you can use a flat head.

 

i removed the area around the screw and finally after 3 days of trying removed it.

--
about the temperature, I cleaned the laptop and repasted the thermal paste "Zalman stg-2" with different method, distributed the paste on the heat spreader rectangle, and now i am getting less than 45C on normal load. mostly 40C

Will try GTA V soon and hope the temps doesn't increase again after a month.

Thanks @hfm @Brent R.

edit: Tried GTA V for some time, not a big change still exceeds 90C

Made a wPrime test, my maximum temperature is 74C

Prime 95 test, temps exceed 90C

AIDA 64 for 30mins, maximum, temperature is 78C

Not sure what should i do now.

 

check your fan profiles.

 

GTAs are usually very heavy on the CPUs with the usually overheating HPs that could cause a problem you can check if you can get a higher CFM fan and replace ur stock fan that's what I did to a friend's HP DV6 and it worked wonders

 

I play GTA V since the release day and that's the first time it exceeds 90C .. any recommendation?

 

Sorry but how to do that? what app should i use?

 

Check your fan profile, elevate the back of the laptop and more importantly find a stable undervolt these haswells come with very high factory voltage on stock clocks

 

install HWinfo and see if you can create custom fan tables.

 

there is no fan related settings in HWinfo

 

there is, you're not looking hard enough. go into sensors, and click on the little fan icon at the bottom.

 

i have the latest version and i can't find any fan icon

http://imgur.com/0mza4Mq

 

probably means you can't control them.

 

I used xtu to undervolt -80 .. Everything is good until the fan work at maximum speed "when the temps get near to 90C after 10 mins of stress test "

The power throttle increase to 100% from 0%

The frequency decrease from 3ghz to 2.3ghz

TDP decrease from 32 to 24

Any idea what's happening?

What's happening is the reason you shouldn't buy a HP laptop.

 

yeah, HP isn't really known for gaming, nor is acer or compaq. i'd sell that HP or let someone else use it and buy a clevo. might have more luck with it than with the HP.

 

okay HP is not for gaming but i still want to know what's causing that behaviour?

http://i.imgur.com/FutM3m0.png

 

Pretty much the official song of NBR right now is "buy a clevo or get burned". As much as I love my clevos it's really sad that I can't even tell someone there's other good choices on the market.

I told you. HP. Likely some kind of BIOS or software lock on the system that forces your CPU to break when it's under enough load or hot enough. Breaking this with throttlestop is manage-able, but all it does is show the poor cooling even more, cause your CPU to hit dangerous temps (and be unable to cool down enough even while throttling) and either you thermally shut down or your CPU gets locked to 0.3GHz until you somehow manage to get the laptop to restart. Shutting it down would be dangerous, because the fan would turn off and the residual heat will not dissipate. Restarting a laptop moving at 0.3GHz on the CPU today is at least a five minute ordeal.

 

okay another question and sorry for off topic.

Should i undervolt processor cache voltage offset? and is there any effect if i decreased processor cache ratio? i want to lower it from x33 to x29

 

Temps-wise it won't help much. Do it if you want though. Cache voltage is a weird thing; it's not a straight shot decrease to temps like processor voltage is.

 

Some reduces the cashe ratio for more stability at high Overclock, not to reduce the temperature. Hardly noticeable.

 

What kind of heatsink do u have?

Is it a shared 1 pipe or 2 pipes over single fan?

 

Have you tried to turn off your turbo boost?

 

That's not an acceptable mitigation in anybody's eyes, honestly. Better he simply limit it to a lower multiplier than 30x via throttlestop or XTU.

 

I know, well underclock is the only solution then.

 

Or sell and buy a Clevo =D
