Sorry Guys I am aware You're trying to get as much as possible from yours CPU's but is it possible to undervolt mobile IvyBridge by XTU?

yea! I forgot thar we were writing about latch missing in 2570p but If i decide to retrofit bezel from 2560p to 2570p there will be only 2 extra holes, am I right?

I browsed again my photos from unsuccessful IPS fitting and I've been wondering whether try it again but with bezel retrofitting. I'm just curious if 2560p bezel is the same as 2570p?

OCed 3840QM and temps under 80C? Madness!

You're probably right cause I haven't had this behavior since this one accident. No no, I just put a second, short heatpipe on the top of original one (I didn't decide to put another one on the bottom), so there is original one and new one doesn't enter the radiator. I'm really frustrated because of this transfer of vibrations. There is strict connection between this noise and bottom plate. Sound appeaes only when plate is set up on its place but I cant find what trasfer this vibration and why one solid plate makes this sound!?

Here are results. I soldered second diode and I got: 255 = 0 200 = 2363 128 = 2363 120 = 2363 110 = 2386 100 = 2457 90 = 2761 85 = 2891 80 = 3110 75 = 3276 70 = 3510 65 = 3723 60 = 4096 55 = 4551 50 = 5015 45 = 5228 40 = 5228 25 = 5228 0 = 5228 nice! but there is something strange. few days ago I noticed strange sound from fan. With constant fan lowfrequencies noise there is something else, like some electric squek. I didn't hear it after first diode soldering. After soldering second diode there is still this strange sound. I started to checkin source of it, by listening to fan with bottom cover and without it. When there was no cover, sound dissapeared. So I concluded that fan moves some his vibrations to cover, because of diode between fan and cover plate. I tried today to solder additional wire to fit two diodes behind the fan, to avoid stick between fan and plate. Even after fitting a diodes between fan and SSD case, strange sound appears after bottom case is in its place. Its extremely weird. I cant find where is the reason of it. I was wondering if it is strange caused by currents but its impossible cause this sounds appears only when plate is closed. I don't have idea to overcome it. Its minor problem cause it's regnosible only when there is no ambient sounds, so only at night. After diodes mode I glued my heatsink. I decided to use option 1 and final is like this: Im not sure if there is any bigger improvement but I got maximum 69C in 3dm11. Without modded heatsink there was 75C. Maybe thermal paste is not ready(?), I used Zalman STG-2. But maybe 6C is not bad, is it? For now, I've been usng laptop for 40minutes with completely turned off fan and I have something like this. Another case, during writing this post, I got almost full battery, and suddenly I was given message there is only 7% left, when I plugged laptop to adapter, I saw 69% left. Could it be caused by fan modes?

Thx for answer. I read about your ways of modding heat dissipation but You and I, have different goals. I need to reduce rpms (-> dB) and maintain (or even reduce) temps after this, You need to create real powerhorse! (second fan is completely unacceptable for me) But If you had to choose, what option ( from detailed above) would you choose?

So why they've been selling it with QM? You wrote that 2570p was in docking station, so You have really good temps. Without docking should be lower because docking cover exhaust exit. Do You mean to cut this part and put bigger and longer one? Im going to dismantle this parts and glue them to the top (where jacobsson put pennys) and second plate will go area where heatpipe is bent. Do You think that's proper way? Ok, I need to choose one option. Which one is better in your opinion? 1) two plates covering almost whole area above CPU + added hetpipe on bending area. 2) two, oryginaly glued heatpipes on the middle of CPU plate + one plate on heatpipe bending area (Im aware that in this dimension on photo there is no option to fit it).

You are second person who discouraged me to use this tape so I'll go with adhesive paste During using 8460p with 2630QM I was able to run all tests with 65W adapter so I conlude that may not be the main reason of crashes. In my opinion, If we want to reduce temps we have to do some vents in bottom case (near heatsink and fan). For me it's very strange that HP created 12,5" QuadCore CPU capable laptop without any vents on the bottem. Take a look on the 8460p/8470p bottom. There are a holes covered with mesh, I've been planing to do the same but I cant find spare cover in poland (I don't want to order from ebay cause in poland, sometimes we are able to find this cover or whole cooling system for less than 10$). I'm going to swap i5-3230M with 3612QM/3632QM but only when I do my heatsink mod (using copper plates (instead of pennys) from VAIO cooling system) and bottom case mod. We need remember that I already have modded fan to lower rpms in first treshold and Im going to solder another one diode to lower rpms wit anothe 400rpms I need to maintain <50C in idle and max 85C with gaming (not Prime test) with QM, If I wouldn't be able to do this, I will be forced to give up with QM. On nbr Aikimox is going to fit IPS screen, he is very capable (more than me) so maybe he will be able to overcome problems found by me during fitting IPS

In Poland people smarter than me, said that they aren;t the same --> ARCTIC SILVER ALUMINA KLEJ TERMOPRZEWODZACY (5g) (3507452909) - Allegro.pl - Wi but they sounds like the same... EDIT: UP ok, they are the same. what do you think about this kind of solution? http://www.akasa.com.tw/update.php?tpl=product/product.detail.tpl&type=Accessories&type_sub=Thermal%20Interface&model=AK-TT12-80

Huge thanks, @phillofoc I already have thow 90W adapters. Im planning to buy 3612/3632 when the witcher 3 will be released Today I was given heatsink from Vaio, for free. I plan to use this plates which was collection heat from CPU and GPU. Bigger one goes in @jacobsson three pennies role. Smaller one will go to heatpipe, where it bends. I have ony one issue, I cant find adhesive compound in Poland

results after adding one N40004 diode. http://forum.techinferno.com/hp-business-class-notebooks/2544-hp-probook-4330s-working-silent-fan-mod.html#post63932

I made an attempt to lower rpms in 2570p. I soldered one N4004 diode, it was a little bit tricky because wire is a really short. It was hard to solder and make it separated from laptop. Maybe I will try tomorow solder one more diode. Even know it's a little bit hard to close bottom cover cause diode is placed on fan. There is no space left to solder two diodes in wire under fan, nearer mainboard. Now we achieved 8460p/8470p rpms level but i'm little bit disappointed I didn't reach 2400rpms like friend above but even that laptop is significantly quieter than before mod. 255 = 0 -> 0 200 = 3072 -> 2700 128 = 3072 -> 2700 120 = 3072 -> 2700 110 = 3072 -> 2700 100 = 3034 -> 2700 90 = 3034 -> 2761 85 = 3034 -> 2891 80 = 3110 -> 3072 75 = 3276 -> 3276 70 = 3561 -> 3510 65 = 3780 -> 3840 60 = 4096 -> 4096 55 = 4551 -> 4468 50 = 4915 -> 4915 45 = 5461 -> 5585 40 = 6144 -> 5851 25 = 6642 -> 5851 0 = 6642 -> 5851 HWinfo after 1,5h using 2570p, on battery, power saving chrome x 7, foobar.

Hi, what is Your average idle temps during normal day, with using chrome (or other internet browser), foobar/winamp, some office sheets after few hours and fan on constant 3100rpm? would You do 3dmar11, performance preset and attach HWinfo photo taken after test? Im interested in temps, CPU Fan and clock frequencies

I put 8 as mutliple number, made save and after this i realized that IB was set as a SB! (1200 vs 800MHz). It was curious but more interesting is that, even after turning ThrottleStopp off, during watching 720p on YouTube there is still exact 798MHz on cores. It's really strange, don't You think?

Does anyone know what the Fan2 is? Don't care about maximum rpms, it is error

Did anyone test temperatures and rpm's behaviour when 2570p/2560p was put into docking station?

I agree with it completely. I used to have this card and it was very quiet and well built. Differences will be noticeable when You choose for example ASUS GTX660 instead ASUS GTX660 TOP OC. Now, You have only very expensive thunderbolt solution as a MagmaBox or sometimes possible to find on ebay, TH05. I'd recommend to choose something better built than S430 (2570p, X230, E6330, 8470p, E6430, T430) and choose, well-known eGPU PCI-E 2.0 compatible PE4L 2.1b adapter. Optimus will work despite discrete GPU (GF), sometimes it needs Setup 1.X to run optimus. In my opinion, there is no point to buy anything above GTX660 if you're not going to upgrade your CPU to QM from M.

As shown earlier, In my opinio there is no point to buy something better than GTX660 without QM CPU (in X220 impossible to get QM). So GTX660 will be good idea, it should be enough to run your desired games in FHD and medium/high details. Yes, PE4L 2.1b ang GTX660 will be best mix for you.

Great Great News! I'm going to aply this mod in 2560p/2570p and 8460p Are You able to asses if it's possible to swap 1N4001 with 1N4004?

The thing is that I decided come back to 8460p after 2560p/2570p because of this 3200rpm in lowest treshold. I really don't like X220 but his 2600rpm in first treshold made him almost completely quiet in comparison to 2560p/2570p.The lowest frequencies in IB are 1200MHz, in SB are 800MHz, it also has influence on average temperatures in idle and stress. It makes something around 2-4C in idle between 2560p and 2570p. Not too much but in stress there are significant differencess, in temp and in dB. So if there was option to make 2560p/2570p more quiet by lowering rpms or by improvement heat dissipation (to switch rpm from 3200 to 0 and maintain average temps around 50-55C) I would choose 2560/2570p.I don't use internal screen almost at all. 90% of time I use external screen (home and work), that's why I dont care about IPS option in X220 and E6220. I made some comparison table, using data from Polish reviews.
