  1. I repasted the ultrabay with Arctic MX2 and did the "unshrouding" of the vents, as shown on this thread: http://forum.techinferno.com/lenovo-ibm/7346-unofficial-y5-410p-cooling-thread-well-mx-4-notepal-x3-testing.html I got zero results. GPU was still maxing at 97-98C. CPU and main GPU were always below 83C so I never touched these. I hear it's a bit more complicated to repaste because you have to disassemble all of it. Repasting the ultrabay is super easy though. Regarding the temperature of the ultrabay, I only managed to bring it down by flashing the unlocked VBIOS and undervolting it -112.5mV with nVidiaInspector. It now maxes at 82-83 without any significant performance impact.
  2. I tried editing the post to fix the attachments, but once I click "edit" I see the attachments fine. I think it's because I'm new to the forum... may be some kind of spam preventing measure. Anyways, I undervolted the ultrabay like you did and my temperatures came down 13 degrees. The ultrabay's max temp now, at 99% load for quite some time (BF3 using GeForce's reccommended settings) and the max was 84 degrees. Quite different from the usual 97! The main GPU, which is still untouched, maxed at 81. And the CPU maxed at 82. So I'm happy with it now. I guess that the CPU won't throttle at this temperature. Neither do the GPUs. I'll have to try out Final Fantasy XIV again, as that one tends to throttle occasionally. So far it's running nicely. Thanks a lot for the tips. Maybe one of these days I'll risk repasting the CPU and main GPU. I only did the ultrabay because I read somehwere that to repaste the CPU I'd have to disasemble everything down to the motherboard and I'm too much of a noob at this.
  3. I just saw now that my phone did some funny thing up there. "I knew around here" was actually meant to be "I'm new around here" So much for google's swipe keyboard thingy! I'm gonna try undervolting the Ultrabay and see how it works out. I did read a lot of posts somewhere else that ppl undervolting the CPU bricked their system. I'm not going to try it out, I'll try the ultrabay only. So just to get it right, you overclock the GPU and undervolt it? Or do you only undervolt it? I took a few pictures of how the ultrabay's GPU looked like when I opened it for the first time. The paste was a bit all over the place, but the board where the GPU sits has some transparent plastic around the die, covering the board itself. There was some thermal paste in the space between the said plastic and the die itself. I wasn't able to clean this up. It's in the picture. Looked dodgy.

  4. Hi, everyone I'm new around here. And new to BIOS mods and all. I repasted my ultrabay AND cut off some of the plastic blocking the air flow to the fans. However, I didn't notice any improvement in the temps of my Ultrabay (which reaches 97-98 easily during play sessions). So I now installed the custom unlocked BIOS and flashed the custom VBIOS on the ultrabay card. My noob question goes to the guys who managed to bring down the temperatures of the ultrabay by undervolting it. How did you undervolt the ultrabay? Can you specify each steps and the amounts? Like I mentioned, I'm a noob and never did anything like this. My only objective at this time is to lower the ultrabay's temperature a bit below 90C to be on par with the CPU and main GPU. I'm still waiting for the mods to approve my posts... Thx a lot for helping!
  5. Hi, everyone I did the unshrouding mods: took some of the plastic off the fan area and removed the mesh covering the grid over the fans. I also repasted the Ultrabay with Arctic MX2. I ran and played BF3 for 30-45 minutes. Initially it seemed like the repasting was helping, but it eventually heated up to 97C. The Ultrabay keeps frying, even with the mods and the repasting. The only thing missing now is the unlocked BIOS to undervolt the Ultrabay. I'm quite curious as to why some people report that the repasting brings their Ultray's temps so much lower and for others the repasting doesn't do anything. Any ideas?
  6. Hi, guys I'm brand new to the forum. I've had an Y510p with dual GT750M for little over a year. I use to mostly to play Final Fantasy XIV: A Realm Reborn. Like everyone else I found that the laptop gets super hot during my play sessions. I've also noticed the throttling, bringing the FPS down to 8-10 for a few seconds and then returns to normal. It happens rarely, so I always thought it was some open app or background process sucking the processing power and then letting it go again. My ultrabay is the biggest problem, as it consistently runs at 96-98C. I read many threads in several different forums where other people tried repasting without any improvements. Then I found this thread where you guys tried undervolting with good results. I honestly can't imagine a scenario where my ultrabay GPU can run below 80C like someone mentioned. The issue is, I'm not a PC guy. I don't know anything about overclocking or hardware modding. Before I attempt some deep modifications to the BIOS and fiddling with the GPUs, I'd like to ask a few questions: 1) how can we undervolt the ultrabay GPU? Is it done with the unlocked BIOS found on the other thread? 2) do we get access to the fans on the ultrabay GPU with the unlocked BIOS? I read somewhere that those fans never work at 100%, even when the GPU is already throttling 3) when I bought the laptop I read somewhere that windows 8 (or 8.1) doesn't like it when we remove the ultrabay component and slide it back in. I read somewhere, I guess it was in the official lenovo forums, that some people had to reactivate Windows because it detected the hardware changes. Did you experience any of this when you repasted the ultrabay GPU? 4) last but not least... if we underclock and undervolt, shouldn't that bring down performance a lot? I mean, if we bring the temperature down almost 20C on the ultrabay slot, I assume this is achieved by greatly reducing the performance. One final question: for best results with the repasting, which thermal compound did you use? Cheers!
