Mates pc hot hot hot!

[mrapoc]

Yea, ive finally built his pc and couldnt be bothered with anything other than the standard amd cooler (and the crappy paste ready applied). Turned the pc on and installed everything...just been round his house to set it up and playing half life 2 looks good Its all good till it starts to throttle (im guessing thats what it was doing) then i checked temps - they were somewhat between 55 - 57. I hope this is because its a new pc and the thermal paste has to "burn in" seeing as though the pc has only been operational for something like 3 hours. Everything else is fine and its set up right. Do you reckon it the "burn in" period?

Sorry to be a pain, but youll need to open it up and put some 1/2 decent paste on. The stock stuff is about as effectvie as fairy dust.

 

[mrapoc]

seriously? oh

, it wont drop low enough? he wont be overclocking - just playing css etc.

if i DO need to reapply the shizzle, what stuff do i need to remove the default "fairy dust" and how do i do it

 

[Ham]

Well in theory 55-57 is ok. But in practice its not, and whent ~40 load could be gaind from such a simple & cheap proceadure.

To remove it people say to use a special TIM cleaner that can be obtained in manya online store.

But that costs money, all i do is wipe the majority of it off the CPU with a bit of kitchen paper and then clean the CPU egdes and small bits with a cottonwool bud or 3.

The HS just rub like hell with kitchen paper (get a clean bit when the kitchen paper is caked).

However youll need to be cearful if you ain't done it before. And make sure your gronded (wristbands ftw).

 

[mrapoc]

well ok, i think i may let him have a play for a bit, ive kept him waiting enough, ill just warn him that the errors we kept getting (freeze ups etc.) were caused by the heat. if it dont go down ill have to tell him that he'll have to live without it for a day

have you tried re-seating the heatsink?

I don't know much about newer AMDs, but surely they shouldn't throttle at 55ºC ?

I wouldn't waste money on any TIM Cleaners tho, just get some isopropyl alcohol/cotton buds coated with isopropyl alcohol(pharmacy) or even something like lighter fluid and some cotton buds. Whatever cloth you use tho, make sure it's lint free. Lots of tissue/cloth leave bits behind.

Not sure about what sort of compound comes on the AMD default, but from what I've seen, compounds don't make 10-20ºC difference if applied correctly. Maybe 5ºC if you're lucky (unless it comes with chewing gum type stuff).

I wouldn't use kitchen roll..

Its got sharp edges.. (for chips)!

I recommend a J cloth slightly damp.. no flooding the CPU .. Just so that it has a bit of fricton between the Geese and the cloth.. REMEMBER EARTH FIRST!

I would definitely reseat that thing. I ran my original 3500+ OCed on the stock cooler and it hardly ever went above 50*C. For cleaning, I just use a paper towel and rubbing alcohol (as equk already mentioned )

Probably something else is wrong, its not the stock paste.

Either the heatsink is not sitting flat, or the airflow inside is really bad or the temp reading is wrong.

I use AS-5 on everything but its only a couple C cooler that the other stuff

 

[mrapoc]

well i clipped it down and pressed the lever down so i cant see what else it might be - the bios and speedfan both had the same reading and we did encounter errors during games which i can only guess was caused by heat

 

[equk]

If it was only in games, maybe the graphics card was throttling?

The CPU temps do sound like the heatsink isn't seated correctly, possibly uneven pressure on a certain side or something.

I know with ATi graphics cards, the fan speed settings in its BIOS seem very wierd, they seem to only put the fan speed up when the core reaches 70ºC which is a bit too late but you can change that in the drivers or even by editing the BIOS.

0ºC > 26%

70ºC > 32%

80ºC > 36%

88ºC > 50%

91ºC > 55%

94ºC > 59%

97ºC > 68%

100ºC > 100%

 

[mrapoc]

well the card was at 50 which is a lot cooler than it was in my old pc which didnt seem to throttle. I may have to go round and put some as5 on it

 

[Rastalovich]

Immediate concern would be with the seating of the sink.

Secondly I`d look at how big a case u`r using and the air-flow therein. If u`r working inside a mini case with a gfxcard that likes to act like a sunbed, a psu that emits like a radiator and a drive/optical that pump some 40-50° - the confinement could possibly add 10° to u`r expectations.

I vote for reseat the heatsink and use some realy TIM in the process, AS5 or that other crazy metallic stuff that people have been talking about... The stuff that XMS used in the last shootout, seems to be good stuff for aircooling/watercooling. I forgot who it was here on the forum but they saw an instant 10*c drop in temps after switching to it, now that's certainly not going to happen in all cases if you're already using something good like AS5 but it will definately definately help.

Ever thought about getting an inexpensive aftermarket heatsink that would be better than the stock AMD heatsink?

 

[equk]

is that metallic stuff the stuff that eats copper?

I know some people have said the compound that comes on aftermarket coolers (grey/silver stuff, similar to the AMD stuff in the image above) is better than arctic silver.

I have the default stuff that came on the arctic cooling freezer7 pro on my system atm, but only because overclockers forgot to send me the AS5.

But now I have the AS5 I've not bothered as my temps are good enough with the stuff that came already on the heatsink.

 

[mrapoc]

well ill try the stock heatsink first with some as5 and hopefully itll be within reasonable temps (57 degrees is toooo hot!) its a thermaltake tsunami case and there seems to be adequate airflow. my reckoning is the thermal paste as it didnt seem to effective when i had to take the heatsink off and it put it on the new mobo (specialtech sent wrong one :noobsign - possibly that was the problem? having to reseat it?

 

[Rastalovich]

I don`t know if the guyz can confirm this, but is there an issue with a stock hsf that prehaps is ageing a bit (ageing probably the wrong word here - prehaps `stored for a while before sold and installed`), that a ""crust"" could form on the paste that`s applied at manuf, and this could be a big issue ?

 

[mrapoc]

it was stored on my side for about a week waiting for the other mobo - i bet this is the problem :noobsign:

edit: just ordered some arctic cleaner thermal paste remover kit thanks again pv

Actually it eats ALUM. I have used it before and it works well but is a REAL PAIN to use (very messy)
