Another cooling mod

I have to start off by stating attempt these at your own risk. I am only showing what I've done so others can benefit from my experience doing these mods. I'll cover my first mod then get to the additional one in a seperate post under the same thread. This is for those who hadn't seend what I had done before.

I run the Q9200 and over clock it as well. I had noticed, and it was confirmed by others, that with Prime95 and even a Q9000 the cpu throttled at stock clocks and voltage. I knew I could not stop this without undervolting but I had to try and at least get it too take longer to heat up. My Idea here was two fold. First increase thermal mass and second to try and cool the heat pipe so that actual liquid returned to the pad in contact with the die.

I purchased a mini GPU heatsink and fan. I then used AS5 GPU adhesive TIM to glue the heatsink minus the fan to the CPU heatsink over the CPU die area. Since the new assembly was too tall I also had to cut out an area in the cover for the new copper HS. This alowed also for some additional air to get to it as well.

With the mod completed at 2.4 GHz and stock Vcore I could run Prime95 for 5 minutes without throttling. Before I was lucky to get slightly over 3 minutes without throttling. Once reassembled I could run Prime95 with TS installed at 2.93 GHz and without overheat for extended periods but it was not something I would leave alone. 2.66 GHz though now was 100% stable and with Prime95 stayed at 85C or under.

Now this mod may have added some weight but did nothing for air flow or noise. The CPU fan just as always seemed anemic at best, not even on at worst. Something I had just accepted until recently.

 

As above attempt this at your own risk.............

I shall start by stating this will increase air volume from the CPU area and this will then increase external noise levels. Also the fan since there is less air flow restriction runs at a higher speed. Still not that of the GPU fan at full blast but a substantial increase you can hear. This should in theory reduce load on the CPU fan decreasing amp draw as a further benefit.

I started the mod by taking the CPU cover panel and removing the ribs to smooth air flow. This resulted on its own in no appreciable increases other than the air volume was ever so slightly increased but nothing to jump for joy about. On the first picture in the above post I notice the small channel to provide air to the fan. I figured this was like blocking the inlet for a vacuum, so it had to go.

So with my Dremel still charged up I went to town. I did not expect that actually this would open more than just the channel but under the bar that is over the network card it opened that gap as well. So say goodbye to any airflow restrictions.

Now with the Q9200 and Prime95 I noticed there is actually a speed stage of the fan that kicks in when all cores are at 91C or greater. With the restrictions before the slight increase in fan speed could not be heard but now it is definitely there to be heard.

I have taken a pic of the mod and then the piece of plastic that was cut out. This mod is only ever required on CPU's that are being pushed well over the cooling systems designed intent. It will not alow you to clock the CPU higher but will give some additional cooling to those pushing to the edge.

So what does this do for me? Well of course there is more noise but as an example I loaded Wprime1024 and at 50% I was up to 101C on one of the cores at 2.93 GHz then shut it down. With the mod at 50% I was up to 95C on the one core and finished to 100% never getting above 97C on any core.

 

Nice work Tanware. Somewhere in a long ago distant past I remember someone else doing a mod very similiar. I think they did the NB also, might be wrong there though. I wish I could remember when and where. They used alot taller HS's and if I remember correctly used those large ball feet to raise the machine up since the HS's stuck so far out of the case.

 

Yes, it was shortly after I did this one. The thing is he never came back nor further responces so I am not too sure about his mod. Even if I could figure out how to get a monster like that too work it would for me make the system unusable.

Truth be told I was not too happy with the first mod. While it did help for as radical a change I expected more. The second mod does what I've wanted for a long time, added air volume. There is little you can do to cool the quad cores but this would probably easily tame a X9100 temps............

 

what is the heatsink model?

 

Got it from new egg...........
Newegg.com - Enzotech SLF-1 Forged copper 1100 Fan & Heatsinks

 

enzotech makes great heatsinks. realy love forged copper. expensive but very high quality.
I've one of those too in my notebook. I had to cut it a bit to make it fit.

 

Yeah, the 100% copper was a huge reason for this one. Copper coated etc just would not have worked out as well. Again the idea was to primarily increase thermal mass. The open fins and slight addded cooling are just another benefit..............

 

Nice mod!

Since im still on my P-7805u with the stock CPU it never goes over 100F, even when gaming... its too bad I only have $9 to my name for the next month or a CPU upgrade would be in order

You should do one for the GPU as well since thats also facing the bottom of the unit


Also, what model Dremel you have! I got my nice new Cordless dremel a few months back!

 

Dremel 8200 Lithium. I had one of the nicad ones before this ubt it has no where near the power of this one. Well worth the money IMHO.

 

@Tanware

Could you have used a small fan for better cooling instead of the copper heatsink.
btw-how do I pm you

 

the fan instead of the copper would flow more air over the internals but not give me the cooling as I wanted to cool and thermal mass the pipe itself. This does have the desired effect but the cooling is still inadequate for the Quad core CPU's...............

 

ahhh
I added copper shims to my gpu and north/south bridge
In my Gateway there is room right on top of the GPU (where other heat sink is by fan unit) to add a small fan on top of the heatsink inside the unit. I measured and the 20mm x 20mm x 10mm fan should fit just fine. I was thinking of blowing the air out from the gpu.

My mod of adding the copper shims to the gpu and the other chip (not cpu) is working nicely as the laptop now idles around 45-50c (with 20+ tabs open in firefox) and so far has not gone past 62C playing need for speed. My CPU temps are low as well.

The copper shims on the GPU and other chip (along with Noctua X1) has done an impressive job.

Can you suggest where I can tap into power for the 5v fan. (I think it's a 1 amp as well).
I was thinking of soldering internally to the usb port on the far right. I plug in my external wifi mouse dongle there so I am guessing that is not a lot of power to not tax or burn out the usb port. Again, where would you suggest is the safest place for me to tap in for power.
thx

 

Safest place for power is the USB. I have heard of a lot of others tapping the USB as the safest method but remember when using those ports you are already tapping some power off of them.

 

Yea, I just caught this thread and pretty much same experience three months ago...

I tried this on my W1101ER with single default fan. The net results was a waste of time.

The heat was dissipated at (now) two locations but single fan still did all the work, heat pipe and the now hotter surrounding air from the copper mod still flowed thru heat pipe. I removed bottom plate and used second fan, on laptop cooler, to blow directly on the CPU/GPU copper mod. This made a difference of 1 or maybe 2C under load, but idle was 5C cooler

I'm more inclined to believe that sound thermal management is worth far more it's weight in copper mods...

 

Where did you get the shims? What thickness? Do you have any pics?

Thermal regulation/temp control is most likely the last mod I can do on this thing.

 

What are your current temps? if you are already within reason then there is no real need to mod. Now as far as CPU and NB you want 1.0 mm more for the NB so if doing the CPU and NB then 1.0 mm for the CPU and 2.0mm for the NB.
