- M17 Heatsink Mod Makes Things WORSE -

So I bought 8 little ram heatsinks from ebay and with them placed on the gpu main sink and they actually raised the temps by about 4C.

Maybe the stock glue/paste/adhesive kajigger isn't very good?.. idk

Anyone know how this could be possible? It seems to me like it should be cooler because the heat has more surface area to dissipate..

 

stock glue/paste/adhesive is the devil!!

 

Definetely change the stock paste. I'd highly recommend ICD.

 

you mod it wrong. the mod works.

 

got any photos Maximus.....Ive never looked back since using thermal tape on the heatsink.....

my cpus idle from 35c -39c and never get above 80c(only when scnaning, unpacking archives) and only hitting 60c - 70c in gaming.

I would highly recommend it.

 

Seriously! Some of the so-called thermal paste out there acts more like a heat insulator rather than a heat transference substance....

 

Paste is not even needed, its all a gimmick

Your temperatures went up for a reason. The reason is this.
By installing the metal shims on the memory, you caused the heatsink to lift up off the core of the graphics card by a small amount. Maybe 50/1000ths of an inch or so. This will cause temperatures to rise, since air is less conductive than metal.
Try using thinner metal pieces, and gauge them so that they fit properly. Than test the temperatures again and see how they are doing

K-TRON

 

please refer to project freeze when talking about cooling of the m17/ocz whitebook
but k-tron here is some pictures of the whitebook opened stocked.
overall pic
here's scook9 modded case cover
here's my modded case
there is the mod that scook9 did
here's halogod's mods

if you want more let me know.

this is how the some people modded there whitebooks/m17 to cool it better which worked for everyone.

i'm in class so ican't pull all the info from project freeze but here's the results from scook9(he was using a cooler i believe so i don't know if it counts or not)
here

here's before i did the mod.
of course i didn't have a cooler so the results aren't accurate but this should give you a general idea of what cooling does.

i can't show you any more pics in class and the teacher is looking at me. but the cover is completely sealed.
this is where the heatsinks should be placed. i don't recommend to put copper or anything underneath any part of the notebook between the hardware and the heatsink EXCEPT the NORTHBRIDGE.

 

LOL physics was never my forte....thanks for the info....

 

dondadah88,
I am well aware of those projects, they are nice day to day projects, but seriously those mods are not professional.

If you want it to be cool, upgrade the fans or custom mill new heatsinks out of copper. Both can be done, and either would be more effective at dropping temperatures

In my experience, the copper used in aftermarket desktop and laptop heatsinks are close to 55-60% copper. You can buy 98.7% copper, it is very expensive. I milled my own custom heatsinks for my homemade laptop project out of copper 3897. Each block cost $300 (3.5" cube). Purity comes at a price, and no laptop computer manufacturer uses them because of the premium one needs to pay.

K-TRON

 

its handy if you are, or like myself related to an electrician or electrical engineer as they can often source this type of high quality copper that K-TRON mentioned for free......my brother has brought me home some really good quality copper and the appearance is immediately noticeable by the look and feel of it.
Problem is the pieces he has brought home so far are too thick IMHO. I could be wrong on that but I want it a little thinner.

 

can I attach them with AS5? or will they just slide off since they'll be upside down when the computer is right side up..

:/

 

You need thermal adhesive paste. AS5 alone wont hold

 

got a link?


Thanks in advance

 

you can get good temps with the M17 without the mod if your not using a quad-core.....just check out these temps with just thermal tape on the heatsink;



and thats a few minutes after an all night gaming session.

 

I've got the 4850's and mine go down to about those temps after "a few minutes" but while gaming they're still going to about 84-90 max, I don't want to see anything past 85ish

 

Really if they're staying at 90 or below you should be happy with that. As you probably will know yourself, quite a few 4850 owners have been having high temperatures whereas your 4850 temperatures are now about the same as my 3870s. (Albeit, I haven't modded at all or replaced stock paste)

 

That's a tall order for these cards. After applying AS5 and running on an Antec cooler I'll still spike at 90 for short periods, though my average is around 80.
