Phanteks PH-F140MP 140 mm PWM, High Static Pressure Radiator Fan
  • Verified Owner
  • Owned For: 1 month to 1 year

3 out of 5 eggs Great radiator fans for silent case, when they work right. 09/05/2015

This review is from: Phanteks PH-F140MP 140 mm PWM, High Static Pressure Radiator Fan

Pros: pros
•Good airflow even with fan grill and radiator
•Silent below 900rpm
•Rubber vibration dampeners built-in
•Sleeved wire with good length
•Sturdy feeling frame
•No "PWM ticking" some fans suffer from.
•Wide PWM range
•Fast support from Phanteks
•5yr warranty
•Supposedly 150,000hr MTBF

Cons: •Frame should probably be more square instead of beveled edges at the corners if these are designed to be radiator fans. Most radiators can tolerate this but some might leak air and loose pressure here. Function over form should win here...
•Phanteks' "Updraft Floating Balance" bearings don't seem as great as they claim. They are just another name for Sleeve bearing and they seem to hold the fan blades rather flimsy. Doesn't seem very balanced to me.
•Quality Control: One fan (out of 2) started making scratching sounds from the bearing after only 6 months. See Other Thoughts for more info.
•I doubt these really will last 150,000 hours, at least not without making horrible noise.
•Almost the price of FDB/Hyrdo/Twister/SSO/SSO2 bearing fans.

Other Thoughts: I don't know if Phanteks recent batch of fans are just awful but after my first went bad, Phanteks sent me a replacement which was even worse right out of the box. Again I asked for a replacement, and this second one started making noise after only a few hours. TWO bad replacements sent back to back is just awful QC. It seems like they're not putting enough oil in the well or they're not being stored properly. It also doesn't help that the well is sealed with plastic so you can't oil them. I sincerely hope Phanteks makes some revisions to their manufacturing process to amend this.

When they work right, these are an amazing value for people seeking silent radiator fans at a cheap price, but I just can't recommend them now due to recent build qualities. I can't comment on what batches Newegg has, so they might work perfectly fine from here.

Other info: I've only ever run them vertical, I wouldn't dare run these horizontal - even if you win the lottery on good ones, it will wear out sleeve-style bearings very fast.

ASUS GTX750TI-OC-2GD5 GeForce GTX 750 Ti 2GB 128-Bit GDDR5 PCI Express 3.0 HDCP Ready Video Card
  • Owned For: 1 day to 1 week

Pros: -Efficient Maxwell design, does more with less.
-Fully enabled GM107 (5 SMM's, 640 cores, 40 TMUs, 16 ROPs, 2MB L2 Cache. GK107 had 387kB L2 cache in comparison so this should be more memory efficient.
-Very quiet fans
-Extremely power efficient
-Additional 6-pin power, reduces strain on motherboard slots and enables higher power ceiling for overclocking.
-Core clocks to around 1.4GHz with bios power/voltage mod

Cons: -Mine came with Elpida memory, clocks VERY poorly, could only get 5.6GHz (+100 offset) without artifacts. This isn't a STRIX card, so you can't really expect the best components here though.
-No vRAM cooling, they could have at least put a couple thermal pads under 2 of the chips which lie 1mm from the heatsink. Low end GDDR5 though so probably doesn't need it. I put my own thermal pads on them, and some ramsinks on the other two.
-Disappointing solid aluminum heatsink and no heatpipes, while it does the job just fine for stock clocks (40c-50c max) it can reach 80c with a high overclock and voltage mod. Asus could have at least put a small copper core above the GPU. The silver aluminum is also clearly visible from a side view once installed. But again this isn't a STRIX, the STRIX version has heatpipes with copper contacts on the GPU.
-Fans feel like flimsy sleeve bearing, doubt they will last more than a year without developing typical sleeve bearing noise over time.
-No fan off mode under xx degrees. Modified fan profile can help here, card idles between 30c-40c, I have fans set to shutoff below 45c. Again this is another STRIX feature here.
-Power Delivery: Standard R68 chokes (SFC i think?) and no Digi+ VRM. Asus blackwing chokes and Digi+ VRM are probably reserved for STRIX class cards, so I can't complain here - these are more than sufficient for such an efficient GPU and should be durable.
-Gen1 Maxwell. Not optimized for VXGI, doesn't support MFAA, no upgraded NVENC encoder, no Third Generation Delta Color Compression. (Not particularly a con with this item since all 750/750 Ti's are gen1 maxwell). This should probably be better advertised. That said, it's still a more efficient GPU than Kepler.
-Price is higher than it should be for this class of card, It should be more like 24 ROPs but Asus can't really be blamed for NVIDIA's design decisions or MSRP. It's still quieter, cooler, and faster than a stock 750 Ti for around the same price.

Other Thoughts: While I listed a lot of negatives, this is still a solid product for the price it's intended to target. People expecting the Asus STRIX features should look elsewhere or do their own custom mods. Haven't encountered any QC issues, seems like a solid card. I'm pleased with the core overclocking potential and the low noise, but knocking 1 egg off for inferior Elpida memory. Bought this while waiting for next gen cards. I really think NVIDIA should have put more ROPs on these to handle higher res though, >1080p requires some significant IQ sacrifices. Probably more optimal around 900p if you want to max out newish games at high framerates (or 1920x800 super wide custom resolution).

*Disclaimer: Dragons ahead. Any hardware or vBIOS modding voids all warranty, I'm posting this below for informational purposes only that may help prospective EXPERIENCED buyers intending to do similar mods. Do not try to warranty a modded card, if you break it it's your own fault and you have only yourself to blame.

With regards to vBIOS modding, this card does 1200.0mV (1.2v) max. The BIOS is kind of a mix between kepler and maxwell since it's gen1 maxwell, so both editors are limited. Power tables 1 and 3 are TDP and power target, can be raised to some arbitrarily high value but >100w may not be safe for long term with 3+1 phase power. Boost table not modifiable, tops out at 1346.0MHz. I set XBAR and L2C to 1400.5MHz to match my GPU Tweak offset of +55. Voltage table modified to provide 1200.0mV (1.2v) for upper clocks. Voltage tables mod:
table 1: 1200.0mV -1200.0mV
table 2: 1175.0mV - 1200.0mV
table 3: 1200.0mV - 1200.0mV
CLK 43 to CLK 63 set to 1200.0mV-1200.0mV so all boosts go to max voltage.
Used latest maxwell bios tweaker after dumping with GPU-Z and flashing done with latest nvflash modded by Joe Dirt. (need --protectoff first)

Thermal modifications:
vBIOS: Temp target raised to 85 (to prevent throttling), RPM11 set to 0, PER01 set to 0 (for fanless mode <45c) and set TMP13 to 85 to keep thermals in check under load (82c max furmark w/ mods). 100% fan can keep it at 80 but not worth the noise.

Physical mods: TIM replaced with IC Diamond on GPU, 1mm thermal pad cut to fit over top two memory IC's with some standard TIM to bridge the small gap. (1.2mm pads might work better). I also put two low profile ramsinks over the two memory IC's near the edge of the card (be careful they won't bump into the heatsink, it's very close clearance. Warning: Asus warranty sticker over one screw.

G.SKILL TridentX Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C10D-16GTX
  • Verified Owner
  • Owned For: 1 day to 1 week

Pros: -Fast 2400MHz at a great value if you catch them on sale, this seems to be a sweet spot that won't limit Haswell overclocks in most cases.
-Low latencies, you can possibly even tighten them some.
-Easy X.M.P profiles, set and forget. If XMP #1 doesn't work, then XMP #2 should and vice versa.
-8GB DIMMs for a possible 32GB with two kits (though these are only tested/rated/guaranteed for 2-DIMM operation, I've never had an issue combining kits before. I wouldn't recommend overclocking to 1T command rate with 4 DIMMs though.)
-Solid feeling RAM, heatspreaders are heavy, very high quality and make good contact with the chips
-Removable top fins for large CPU heatsinks
-Lifetime warranty, and excellent G.Skill support.

Cons: -Doesn't seem to overclock past 2400MHz even with higher latency but this is to be expected nowadays. RAM is binned very tightly. Want faster, pay more. your mileage may vary, it could just be my CPU or secondary/tertiary timings.
-These are double sided/dual rank DIMMs, not really a con as most RAM is these days, especially with 8GB modules. I only mention this because some reviews mentioned single sided, which is probably the 2x4GB kits. Single sided/single rank has slightly lower latency since the memory controller can't access both banks simultaneously in same same clock cycle with 2 banks but in dual channel you have two interleaved 8GB banks basically, and the memory controllers should be smart enough to manage them well. I can't really see many single programs needing >8GB RAM access simultaneously and at this speed I doubt it would be an issue.

Other Thoughts: Bought this kit to replace my old 2133MHz G.Skill Ripjaws X for my Asus Z97 Haswell system, very pleased with it. I was able to lower to 10-12-11-31-1T @ 2400MHz with default 1.65v.

I'd heard this RAM really shines at 1.7v but I wasn't able to push 2600MHz at 11-13-13-35-2T 1.7v even with VCSSA, VCCIO, and VCDIO raised at stock 4790K clocks. I was hoping for 2600-2800 at decent latencies but I knew what I was buying so I can't fault the RAM for that. Overclocking is never guaranteed. G.Skill bins very tightly, but the latencies are a bit over-conservative for broad compatibility. Might work at 2600+ with 11-14-14-35 though.

I noticed my Asus board had pretty high secondary timings on "Auto" which I adjusted from reading the RAM's SPD. Passed 12hrs Memtest86+ with 10-12-11-31-1T with secondary timings manually set to G.Skill's SPD of 6-313-26-9-26-7 (tRRD tRFC tWR tRTP tFAW tWCL) but I'm using XMP #1 which I assume uses tighter tertiary timings. Not sure what to set tCKE to, but my board Auto'd to 6. I might need to raise timings again once I overclock my CPU.

Also, not having a 1600MHz profile is not really a con as someone else mentioned. I assume G.Skill didn't have room for it in SPD since they have 2 XMP profiles. I bet this would run fine at 9-9-9-24 or even 8-8-8-22 @ 1600MHz. Possibly even 7-7-7-20.
