    Acer Aspire 5220 - heatsink = JUNK!

    I've just gotten one of those in for reflow. It's been done just 1.5 months ago (by someone else) and it failed again. It would start, run for a few minutes, then crash with a garbled screen.

    Taking it apart reveals piss poor thermal design. No joke. The GPU on this model (nVidia Geforce 7000) is integrated into the chipset and uses shared memory. The heatsink has screws only around the CPU and the fan. The chipset/GPU is in the middle and relies solely on pressure from the other parts. Good job Acer. Also the thermal pads used are crap and whoever reflowed it reinstalled the same pads.

    After reflowing GPU works fine but it sits at 70C at the desktop. And the thermal control for the fan monitors the CPU only. Good job Acer. Time for some mods.

    Yeah. Same problem here. I reflowed it and it worked for a day. Then froze on shutdown and never turned back on again.

    Waste of time IMO, these laptops are doomed.

      Well, looks like this one has been given a new life. I made an aluminum shim for the GPU and temps are at 53C at the desktop and 70C under FurMark. Much better.

      However i ran out of thermal paste for the CPU, i'll go buy some tomorrow morning.

          I tend to disagree with this statement why is it when AMD had heat problems we blamed it on AMD CPU architecture yet when GPU gets too damn hot which was seen on numerous laptops not just ACER we tend to blame it directly on the laptop manufacturer ... Good example look at all GPUs alike the HP DV2000 through 6000 they had worse luck then ACER did can't imagine why HP is not to blame though but yet folks cast stones at ACER I think its great cause it keeps the prices low on these units personally so I can rake them up and use them at highly discounted prices but I just find it funny really the GPU's from Nvidia were not designed well for the use in laptops knowing the cooling that was being used believe it Nvidia had a hand in specifics of cooling requirements and I'll bet money that the makers of these laptops would not finalize the product without heeding these warnings look at amd working with laptop makers now for there new flagship fusion technology it will not be much different the designs are seen by all parties at some given time or point and the coolers are roughly the same in all laptops no matter if ATI or Nvidia for the most part ATI now being AMD...

            Eh. It is not entirely nVidia to blame as well.

            nc82x0 series was doomed as well. If it was not for GPU it was for shitty intel SB chip.

              Just had to reflow my DV2000 and a DV9000 yesterday. It is the 3rd time for both of them. I told the owner of the DV9000 that if hers does it again, I am going to replace the board with a DV6000 Intel that don't have Nvidea Chipset on it.

                thanks dobber for the confirmation reflowing is a pain in the but but reballing is even a bigger pain ... Those Nvidia GPU's were not market ready I'm telling you they ran to hot to be in such a confined space with such limited cooling options for mass production at that point and time. ATI had similar issues around that time but it was not anywhere near as bad and it seems that reflowing was more successful with the ATI as luck or what ever you would like to say would call it.

                Just to let you know I love Nvidia cards and ATI cards alike just like I love Intel and AMD alike I will say at one time or another the architecture of all of these manufactures chips ran to hot. Intel was the Prescott era AMD was the xp era AMD was the mobile technology era that we are discussing ATI was the same era but never was much more limited maybe it was fabrication processes being used at that time were the real issue I really don't know for sure all I can do is speculate but it seems that for CPU's and GPU's both happened at around the same time or shortly after its rival which is what leads me to suggest the fab process was somewhat flawed so it is an educated guess at best to make my suggestion.

                  I don't think it's entirely nVidia's fault. They don't run alarmingly hot if they have proper thermal transfer material installed. Which they do not. Instead they use those lame little pads that can barely transfer a chip of RAM worth of heat, let alone a full-blown GPU.

                    Re: Acer Aspire 5220 - heatsink = JUNK!

                    Has anyone tried using Rivatuner to max out the fan speed. I downloaded it and was going to see if this helps with the overheating. On the DV2000 I did add more air holes to help with the flow of air, but still think that maybe I could do more with the fan. Also I was thinking maybe a micro fan by the video chipset if it will fit?

                    PS By the way, I also do not think it is all NVidia's fault. I think that HP could had much better engineers, but we live in the age of throw away PC's now. When I worked at Gateway, I was always fighting with the engineers that think it has to be there way. But as we know, they are not always right in real world situations.

                    Also If I am right, I think that the EPA is part to blame also with the requirements of the more tin based saulder verses Led.

                      Okay, this is ridiculous. I left it aside for a few days and now came back to it to put everything together and give it back to the owner.

                      NO VIDEO. WHAT??? Yup, it's dead alright. It died doing nothing. And it isn't the GPU because i tried reflowing it again and it behaves exactly the same. Besides, it was properly done in the first place. It's not the CPU either as when i put poor quality thermal material on it the fan goes faster, so the CPU is working.

                      What a heap of junk.

                          Hi, I'm from Brazil, new to this forum and this is my first post, hope I can help a bit.
                          The problem may be with the reflow. You can't control what is going on under the chipset, with the solder, it may be shorted at some point, so the best way is to reball the chip (remove the old solder and apply new one). I've been doing motherboard repair for 4 or 5 years now and after I started reballing I got no returns.

                            Yep, reballing will also adress any issues with the lead free solder ACER used being shite.

                              Actually the problem is 50/50 from Nvidia and laptop manufacturers. The solder used in the lead-free crap, which replaced the old good lead solder. The good thing with the new one is that is more environmentally friendly and for us healthier. BUT, the early produces of it weren't exactly perfect. Under heavy temperature changes (e.g 3d games etc) the materials contained which are contained in the solder don't expand and constrict (i hope this is the right translation, i'm greek :P) the same time, so after a while cracks appear at the bga of the chip and then death. Did i confused you? Sorry... i must take again english classes...

                              Adding that to the fact that many manufacturers didn't take count the vga temp (so the fan only spins when the cpu heats up), others used that stupid and useless thermal pad and some just couldn't bother to make a good heatsink (hp dv6000/9000, the heatsing is not verticaly aligned, clevo m66sru uses passive cooling for the 8400GS!!! etc) and... poof!

                              The only real solution is bga reballing, but a machine for that costs a lot. Reflow can work but for some time (with come extra caring my dv9000 is working for more than a year with heavy gaming).

                              Some sollutions are : If possible force the fan constantly on, Use copper instead of thermal pad and artic ceramique where possible and for the 8600 users (you poor guys) disable 3D modes with rivatuner.

                                The problem with the lead free solder happens only on BGA chips, here in Brazil we reball using leaded solder and we have almost 100% of recovery level. The company I work for has been reballing motherboards since 2006.
