E1705 cooling

Are there any cooling solutions for these?

For example does anyone know if I can order just the dual pip heatsink, or maybe some better fans?

Also, as far as I know the heatsink on the stock 7900GS is aluminum, wouldn't a copper one be better?

I haven't put thermal paste on ANYTHING for atleast 9 years, is it hard to redo the thermal paste with something a little more high performance?

 

well, the easiest way is to get a cooling pad.(~$20-50)
as for thermal paste(such as Artic Silver); it's mildly difficult, that is you don't want to make a mess or break anything while doing. the think about thermal pasting is that you want to check and see if the CPU is soldered in or not. If it is then the paste is a no go.
other cooling techniques include undervolting, and using programs like NHC to control the performance of the system, as well as Speed Fan, and I8K.

 

Well, this is more for my GPU than anything.

It's the only thing that ever really heats up.

 

most laptop GPUs I've seen aren't like desktop units so it's harder to modify them, but not impossible.

like I said before the easiest way is to get a cooler and a program like NHC

 

I'm already using that.

I wish someone made aftermarket laptops parts.

 

I8kfangui will be your first starting point to better control the 2 fan and there's a how to in applying artic silver in the forum as well.

 

its pretty hard to find a cooling pad for the e1705... maybe im just too picky but it seems like theres no pad out there that are larger than the e1705 dimensions...

 

you don't technically need a larger one so long as it creates a gap between the bottom of the laptop and the surface of the cooler

 

My cooling solution was to buy an iLap (kind of pricy but well made) and use a Vornado Zippy fan to blow air on the back. I didn't trust (and I tryed) a laptop cooler (not Antec) with fans that have two tiny corners where your laptop rests.

 

Be sure to keep the vents clean.

 

Will do.

I'm using a riser pad, it kicks up the back of the notebook about a half inch. I've got about 300 hours on Oblivion and other assorted games on my OC7900, no problems.

The pipe is copper, the fins are aluminum but wish Dell used dual pipes on all their 17" notebooks.

 

This is the cooling system that I use: http://img.inkfrog.com/pix/wahmanwah/IMGP1555.jpg

It works pretty well, reducing temps by 5-8C and draws air from the 2 fans and blows it out underneath, cooling the notebook base and powered via USB. Your notebook is elevated while resting on the 2 black triangularly shaped pads.

 

That looks reasonable..how noisy are the fans?

 

The problem is the heat when I do the overvolt mod for games like Stalker.

I think I'm going to do the artic silver mod maybe next weekend and see how that works out.

 

Do us a favor and log your GPU temps before and after and how quick your fans go into "high speed". You can use I8kfan to log for you.

how much does one of those fans cost jujube?

 

Oh, I planned on it.

Right now, without any modification running a volt mod only CERTAIN games make it heat up crazy.

Stalker and Test Drive (When it worked) make it shoot right up to 80, then it slowly climbs to about 89 and I minimize and let it cool down.

I usually play stalker unvolted just so it won't do that.

 

does anyone know how much jujube's fan costs?

 

I use a desktop fan to help cool my E1705. It sorta blows over the whole laptop, but some of the air gets into the side GPU vent. Ghetto, but works for my overclock (600/750) on a single pipe 7900 GS. With the fan off the GPU idles at 65 and with the fan on the GPU idles at 60. (This is with the GPU fan on "slow" in i8k)

 

I too use a 5" 24V fan. The fan blows tons of air across the laptop, and cools down the laptop instantanly, I OC the GPU as well and so I need the cooling. It can bring the cpu temp of 75celcius to 45 less then 3 minutes. This is way more effective than ANY laptop cooler i've ever seen. The small inefficient fans aren't strong enough to move large amounts of air..

 

I use an 8" desktop fan and a pair of drum sticks. It gets my temps down to the low 30s and upper 20s F.
I was just curious about the price because I have never seen such a big temp drop from a cooler.

 

I'm running around 83C {with +8C offset} with fans on high after a few hours. If I kick the ceiling fan on I drop to about 79-80C.

Dell ships the 130 watt supply with the XPS so I do not want to overheat my dinky 90W supply with additional volt mods. If I can find a break out plug i could check my current at different clocks but brick runs way warm at my current clock in SIG. If I find time i would try the AS. Let us know

 

My e1705 runs about 75C (adjusted +8) after heat soaking with ATItool's hairy cube. I have the Notepal Cooler Master running two 5V fans from USB, and my laptop fans running full speed. Since the E1705 runs for about five minutes on battery power, you'll more than likely always be near some AC power outlet. This means the sky's the limit on cooling solutions. The e1705 does a tremendous job cooling itself, but there is NO room for any additional heatsinks or other contraptions in there. It also doesn't help that the keyboard directly above the GPU has a foil-like reflective surface that does a good job of reflecting heat right back at the GPU. I have tried everything I can think of for USB powered cooling. The results are not worth the trouble. If you'll notice, the panel that covers the RAM is roughly the same size as a 120mm fan. I got temps down into the low 70's with the 120mm sucking air OUT of the lappy, and no change when the fan was blowing air into it. It is too hard to rig it up like that though. Having a fan blowing air on/around your laptop is going to reduce temps. Lowering the ambient air temp will help too. You're going to get the best results by cooling the whole laptop versus just pulling/pushing air across the heatsinks. The 120mm fan at the RAM port circulates air through the entire laptop, so I am going to continue to experiment to find some way to use that reliably while gaming. Also do make sure you go in there about once a month and clean your heatsinks and fan of debris. Especially if you have household pets. Just today I pulled my lappy apart and found gobs of cat hair in both of my heatsinks. Running about 5C cooler just because of that. Also, you don't need some expensive laptop cooler, just keep the laptop elevated so the fans can breathe. The intakes are on the bottom. Hope I could help. As you can see, I am very interested in cooling solutions as well.
