The base of the laptop feels very cool. Toshiba's power settings (cooling mode -> battery optimized) seems to have no effect on fan behaviour Fan starts a few minutes after system bootup (35 degree startup temp?) (supposedly could set fan start and stop temps) NHC (notebook hardware control) seems like might work if you know C#. Speedfan and other utilites not supported. Well here's my contribution to start the list!Ĭentrino Duo T2500 (2Ghz), Geforce 7600 GO 256MB Here's my (slightly extended) review of mine (now returned). Also feel free to give subjective noise impressions, e.g. Please post info like default start and stop temperatures, bios options of interest, and the model number you got. Would have even better passive & oc capabilities if it has the dual heatpipe cooler for the VGA card (found in the xps version)8.7 /10 - cloneman This laptop overclocks very well (without affecting it's clocks in powersaving mode). Both fans are quieter than the 6400 model's fan, & the GPU fan is barely audible over the HD. Impressive acoustics for a desktop replacement. Coil whine can be controlled & minimized, but is present. This results in a more efficient operation and the possiblity to cool almost completely passively on idle. Uses 2 heatsinks and 2 fans to cool the CPU & GPU seperately. With better fan control this would be excellent. Laptop base feels cool on your lap, could definitely survive much higher temps. Fan turns on after a few minutes of use, and will never turn off after that. Fan is noisy, easily audible at 4-5m away. Toshiba a100-sk9 (15.4" wide, Core Duo 2Ghz, Geforce Go 7600) Not safe for passive cooling, but reasonable overall, though not close to SPCR standards. Hard Drive I consider somewhat loud for home use, but not noticable in an office environment - steve8pi With FanGUI set for 55/47, still cycles, but less often. 7/10 - clonemanĭell Inspiron 6400 (15.4" WS) Core 2 Duo, T5600 (1.83 GHz) with ATI Mobility Radeon on/off at 48/38 If the fan control would allow lower rpm it would be much better. It's dependant on load and speed/voltage control. A coil whine howeever seems to be present, and is piped through the sound card as well. The hard drive (120GB WD, reviewed on this site) is definitely audible, but not intrusive. Fan does not need to go higher than its first stepping under most use, (2400rpm), and its fairly quiet. With the fan off, temps will rise, even undervolted & idle. steve8piĭell Inspiron 6400 (15.4" Wide, Core 2 Duo 2.16Ghz 667FSB, Mobility Radeon X1400)įan control is supported by i8kfangui. Bottom gets warm, and rear of keyboard, next to display. Uses a Celeron-M 1.3GHz, and fan doesn't run until I do some intense computing. When placed on a desktop, temps never exceed 55C and usually hover around 50C. Using I8kfangui, I've set it to switch the fan on low only when temps hit 60C. Top of the laptop and palmrest never gets even warm, though the underside of the laptop does. clonemanĭell Inspiron 2200 (1.3ghz CelM, Intel GMA900 768ram, 40gb)Ībsolutely silent. Not yet tested in ideal quiet conditions. Fan spins up seldomly and is reasonably quiet. IBM X40 (12.1", Low-Voltage 1.4Ghz P-M, Intel Extreme graphics 2) Everything goes here, the good, the bad, and hideously loud. NOTE: This is not a "recommended laptops" list. The list! (i'll just keep editing this post as you guys post info) As long as it can stay under 60 though, it's a sensible choice for a low-noise laptop (all other things being equal). They are seemingly a big liability still in laptops.Īlso good would be a laptop that can idle at 50 degrees or less without active cooling. I have yet to see the mobile GPU market really kick down the temps when their cards aren't doing 3D. The holy grail would be a laptop that can stay below 60 degrees without help from the fan for light loads, yet still sport a powerful video card. Contribute! See examples below.Ģ) Fan behavior (default start/stop temperature)ģ) Support for speedfan, or other fan control software, and how it can improve the noise level.Ĥ) Does the mnfr power management utility or bios help?ĥ) Subjective (or measured!) fan & harddrive noise levels & character The following easy-to-acquire info can really help to evaluate the quietness of a laptop IMHO. Usually this is only achievable with software controllable fan speeds. Many of us (I would think) are looking for notebooks that can be cooled passively for light tasks, and quietly under load.
