Quick practical add-on for (and anyone with an Intel D915GLVG): the board provides a 4‑pin processor fan header (PWM) and separate 3‑pin chassis fan headers. The manual explicitly says the processor fan must be on the processor header (not a chassis header) and lists the connector current limits: processor fan ≈1000 mA, chassis fans ≈600 mA. (manualslib.com)

What that implies in plain terms: do the math before tying several fans to one header. If the sum of the fans’ current draw exceeds the header rating, either power the extra fans from the PSU (Molex/SATA) or use a powered PWM hub that draws its power from the PSU but accepts a single PWM control line from the motherboard. Simple Molex/SATA hookups will run fans at full 12V (no motherboard speed control); powered PWM hubs (example: NA‑FH1) let the board control speeds while supplying the extra current. If using splitters, make sure combined current stays below the header limit. (noctua.at)

Short checklist (complements earlier replies):

  • locate the exact fan headers and their labels in the product guide (see the "connect fan cables" figure) and note which are 3‑pin vs 4‑pin. (manualslib.com)
  • prefer a powered PWM hub for multiple, quiet, controlled fans; use PSU adapters only if constant full speed is acceptable. (noctua.at)
  • keep the processor fan on the 4‑pin CPU header and leave BIOS processor‑fan control enabled (the manual recommends this); the manual also points out local high‑temp zones (VRM area) to watch if temps stay high. (manualzilla.com)

This expands on points from and about case airflow and on ’s note about thermal interface — it explains how to safely supply and control additional fans on the D915GLVG without overstressing the motherboard headers.

You can buy fans of diff size and color at alot of place's Best buy place's like that.You should have a spot for one on the case in the back just get one that will fit in the spot..on the you can drill,cut,carve pretty much anything you want in the cast lol..most of them are made for best venting with the hole's suppled in the case...I would just throw one more in the back...hope that helps...

I'm assuming this is your CPU's temp?
Chances are your PC is not getting enough ventilation. Here are some tips:

If you have a steel case -- invest in a aluminum case!! These conduct heat better and will not get nearly as hot.

Get a bigger case. The more room inside for air to spread out the cooler it will get. It also allows for you to put fans inside.

Make sure you have a good cooling system.

Make sure your PC isn't located in a corner of your room, or in any place that it will not get good airflow. If possible maintain a constant room temperature of about 70 degrees F or so.

Make sure all your hardware is working properly. Check on the CPU fan to make sure it's running properly.

Check the thermal paste (is that it?) on your hardware. The stuff sometimes thins out.

Make sure there's nothing blocking fans.

Put in more fans.

Hope these helped. I'm not an expert, but thought some of these would help. I own a Lian-Li case... really nice. Worth the extra money.

suggest making sure the case, heatsink and fan are dust free and running well. you can also carefully lube the fan by peeling the centre sticker back and putting a TINY drop of sewing machine oil on the spindle, leave for 10n mins to penetrate, put sticker back and replace, i've done this many times. also carefully remove the proscessor, clean the old thermal paste off it and the heatsink (good pc store can supply an appropriate solvent) put new thermal paste on (about a small pea size will be plenty). if it was running ok before this should sort it.
