Liquid Ultra application

Hi , I know a few of you have used this for there Cpu Mr Fox being one of them , my question is on my 4910mq there are contacts running down the side of the core and was concerned if this stays liquid is there any chance it can leak onto the contacts and short the Cpu ? , did watch a few vids but mainly on desktop variety not for the smaller die laptop type , did apply some tonight quite a thin coat , covered the core evenly but I am getting worse temps than before , so my question is how much do we need to apply to these cpu ? , I am assuming I did not put enough on hence why the temps are worse ..anyway anyone who has used this please could you enlighten me on the best way of doing this ...thanks in advance

 

I'd imagine the risks are the same with a laptop heatsink setup and a traditional motherboard.

I am going to get some so will share any experiences I have if useful, I'd imagine you haven't used enough. The amount of application would be the same as a normal CPU so check out the youtube Videos from Coollaboratory

 

Yeah Thanks , will take it off today and have a look and if it is still liquid will just add a little bit more , my temps are not bad , but I do find there is a fair bit of temperature difference between the inner 2 cores and the outside cores for example on real temp my temps vary like this
56 58 57 52 and the hotter it gets the middle 2 end up being maybe 6-8 degrees higher than the outside temps ...anyway will add more and if not happy will just put ic diamond back on and have done with it

 

Take a picture after applied and upload here.

 

Yes that sounds like it's not evenly applied - give it some more and don't worry about it shorting out the motherboard. They couldn't make a liquid metal thermal compound that shorted out the system - I imagine it's not conductive or it wouldn't have passed Quality/Safety tests and others would be complaining that it shorted out their systems.

 

Hi Mr Pras , unfortunately yes it is conductive hence the worry hahahaha , but have applied some more and seems better now , this time I applied only to the core and not the heatsink as well , my temps are still a bit inconsistent but maybe that is down metal plate over the core not sitting right , have seen guys with desktop cpu remove the plate and re-paste inside effectively making a big difference but I do not think I would risk it on laptop cpu...ran the wprime 1024 at 4100 and was around 5-8 below my previous with ic diamond but little bit concerned as to the fact it is conductive and if it stays liquid can it leak out the sides and kaboom !!!

 

Ah okay sorry about that.. What I'm maybe going to try is apply the liquid ultra as normal but put a thin line of AS5 around the edge of the connective element of the CPU (making a little dam if you will).. Perhaps I'll also try dripping some wax on to the exposed copper dots on the top of the CPU package.

I'm glad you've got it working! I guess the idea is to have as little as possible and yes thanks for the heads up regarding it being conductive.

 

I have used Liquid ultra now for over 1.5 year without problems on my i7-4930mx and with very good results. You must use it on both cpu die and heatsink if you want the best results with this paste. You can't have a big gap between die and heatsink if you shall use this paste. Don't be worried about applying to much of this paste.

 

Thanks for your reply , was just concerned that the material could leak from the sides when screwing down the H/S ,by the way on the syringe how much did you use on one application .Cheers

 

There is a big difference to shave or cut off your head . Everything in moderation...Used about a third of Liquid Ultra syringe. Should be enough for 2 applications extra if I need it. But it does not look like I need it . Very good temp on my [email protected] all 4 cores. Idle at 37-39 degrees Celsius. Moderate Internet/office use is 42-44 degrees Celsius. Rarely over 67 degrees in heavier use. Wprime 1024 stress test(167.657 sec) with +91w from processor provides maximum 89 degrees Celsius. http://hwbot.org/submission/2849851_papusan_wprime___1024m_core_i7_4930mx_2min_47sec_657ms Cinebench 11.5 give me 9.42 scoore and 84 degrees max processor temp. http://hwbot.org/submission/2852931_papusan_cinebench___r11.5_core_i7_4930mx_9.42_points Remember that 6-8 degrees difference between the coldest and warmest core is completely normal.

 

Thanks so much for your reply , much appreciated , well have done what you said and all good , but I think I will stick to around a constant 4ghz serves me just right ..you have a good day and Cheers
